ChartControl Issues [34][Solved 14]

Hi,

1.  Label doesn't show (ones with very small values) anymore if one of the bars (StackedBars) has a very large value. If Rotated (Horizontal) it works OK (even small values will show labels) Example bar1 = 1 and bar2 > 100000 [Fixed in V15.0]
2. [QUESTION][SOLVED] Why can't I use an array value for the argument when adding Points. See following code (note: without CStr it shows only "zero's"
   • With .Series
         .DeleteAll
         .Add ("Aangeboden kaarten")
         With .Item(0).Points
             For i = 1 To UBound(myArray)
                  .Add CStr(myArray(i, 1)), myArray(i, 2)
             Next i
         End With
     End With
3. [BUG] When using for example Pyramids small values don't show either (something they show and sometimes not) The "gap" between the layers is almost nothing (I would expect assigning .PointDistance = 20 would make a difference but it doesn't) If the legend shows some value I would at least expect to see a line (1 pixel) for it.
4. [PROBLEM] The labels are drawn onto each other with small values. Maybe positioning labels ourselves? Or some property that labels would be positioned with certain value from center? See image 1.
5. [BUG] Pie2D, Pie3D, Torus3D Charts drawn incorrect when having a small value (1 pixel???) See Image 2.  
6. [BUG] Pyramid3D drawn incorrect when rotated with mouse. See Image 3. [UPDATE] Also Image 3a
7. [QUESTION][SOLVED] Is it possible to create scrollable chart with bars.

8.  Pie not drawn with a single Point. Only shows label. [Fixed in V15.0]
9. [BUG] Since scrollable chart is possible, I found that, once you scroll to "next page" and setting different value for ViewMaxValue, view isn't updated like should. See test project (I will use this for every other issue I find) 
10. [BUG][SOLVED] Scrollbar doesn't disappear (once scrolled to top, bars are horizontal) after setting different value for ViewMaxValue. If scrollbar is set to the bottom and ViewMaxValue is set to number of bars that could fit into the view, scrollbar disappears (this is how it should work)
11. [QUESTION][Not implemented] How to get color of one particular point when ColorEach = True. Seems .Color is returning always zero...
12. [QUESTION][Answer=NOT possible] ColorEach property is using palette colors, right? How can I find out how many colors one "palette color" has? (prefer in code and not by checking each color manually )
13.  How to create a palettelist? [Added Palette Class in V15.0]  
14.  [BUG] Customlabels are still visible when scrolling, it disappears only at the bottom of the chartcontrol while "normal" labels disappear when below min / above max. 
15.  How to set scale above the maximum / below minimum value of a chart (WITHOUT adding a negative point value) ? For example a bubble series, the maximum bubble value is partially outside the view. I would like to see entire bubble. Same with small values the bubble shows only partially and the label doesn't show...  
16.  Following code throws error: Object variable not set ..... [Fixed in V15.0]
    • Dim BubbleSeriesStyle As New ChartBubbleSeriesStyle
          With BubbleSeriesStyle
              .MinSize = 1.5
              .MaxSize = 3.5
              With .Label
                  .ShowLines = False '????
              End With
          End With
17. [QUESTION][Answer=NO] Is it possible to position the label with Bubble series to other position besides to center of bubble? 
18. [QUESTION][Oleg said: Adding support of proportional bubbles] When assigning values to BubbleSeries, the width (in my case) is set same as the value itself. Is this the right way or do I have to calculate the width itself to get proportional bubbles? I'm asking this because the smallest bubble isn't in proportion with the other ones. See Image 4.
19. [QUESTION] When Diagram is rotated, the scrollbar is still showing while contents fits easely in Chart. Changing .ViewMaxValue doesn't do anything unless the scrollbar is positioned to the left (or bottom when rotated) I have a strong feeling this has something to do with Issue#9. Please, look at the testproject again.
20. [BUG] xtpChartPyramidLabelCenter doesn't work for 3D Pyramid, labels don't show.
21. [QUESTION] Selecting appearance "Black" the label borders don't show anymore. Correct???
22. [BUG] Pie3D, Doughnut3D and Torus not rendered correctly when having all points set to special. Left and right side is a part missing. See Image 5.
23. [QUESTION] I need to display percentage for each slice of a Pie. Do I have to calculate value myself? If so, could we have a property that contains calculated percentage value? You already calculated percentage to draw Pie slices so exposing this value is easy. Maybe .Format = "{P}" is an option...
24. [QUESTION] Is there a way to create something like this? I tried but the only thing I get is a ONE row with pies and the more pies I add, the pies getting smaller and smaller.
    • 
25. [BUG] Torus (when rotated with mouse) is showing a "hole" see Image 6. & 7. (Update: same with Pie3D and Doughnut3D) Under certain conditions the bug occurs. I have an option to show/hide legend AND to show/hide labels. Setting one of these options to true/false you get to see this behaviour. You also see that the pie gets resized again after the legend is set to false maybe this is problem... Another update: Seems only exploded points are having this problem. You can reproduce this with your own ChartBrowser sample: just set Labels visible to false and rotate Pie3D, Doughnut3D and Torus with mouse. 
26. [SOLVED (mysteriously)] Updating Diagram2D after creation of certain style doesn't do anything if I don't use DoEvents before calling the RefreshDiagram function. If I use DoEvents before updating diagram it shows all items but I see a flickering (because I want to set different min&max Range values) I don't know what to do anymore. Maybe I'm using it the wrong way so any advice on this would appreciated. Test project: uploads/3701/Charting_Tool.zip Update: If you would set breakpoint on ShowChart and resize window so you are able to see application and IDE and proceed with F8 (until both functions have been carried out), you get to see every point added in application and Chart is rendered correctly.
27. [BUG] When resizing Chartcontrol with Pyramid style at some point it will be rendered the opposite way looking like a funnel  (first it will be invisible but resizing it just a little smaller it shows above behaviour)
28. [BUG] Legend is drawn over the border of the chartcontrol when resized smaller. Well almost everything is drawn over border...
29. [QUESTION] Why is PointDistance for Pyramid2D and Pyramid3D rendered differently? With Pyramid2D the space between two parts is smaller.
30. [BUG] Tooltip for bubble doesn't show because the label is centered over (small) bubble. If label isn't visible the tooltip does show.
31. [QUESTION] Tooltip doesn't show with Pie3D,Doughnut3D, Pyramid3D and Torus, correct???
32. [REMARK] ChartControl.ToolTipContext is problem. I tried with following, maybe it's always like that... Just noticed it trying to set a tooltip for a Pie slice. note: There are a lot of items added into the tooltiptext with vbNewLine 
    • xtpToolTipStandard 'Blinking tooltip window
    • xtpToolTipBalloon 'Blinking top -> middle -> bottom  tooltip window
    • xtpToolTipOffice 'Top outside screen
    • xtpToolTipRTF 'Top outside screen
    • xtpToolTipLuna 'Top outside screen
    • xtpToolTipOffice2007 'Top outside screen
    • xtpToolTipHTML 'Works OK
    • xtpToolTipMarkup 'Top outside screen
    • xtpToolTipOffice2010 'Blinking  tooltip window
33.  How to create PrintPreview for Pie3D, Doughnut3D,Pyramid3D and Torus [Fixed in V15.0]
34. [PROBLEM] I have a problem I cannot reproduce with ChartBrowser sample. In my own application I have ChartControl, Commandbars, DockingPane, SkinFrameWork and PropertyGrid control. So I thought this might be problem with CommandBars (because I use ResizeClient event to resize ChartControl) So adding Commandbars to ChartBrowser Sample and adding same resizing event from my own app didn't change anything. So I added all controls I have in my own app (except PropertyGrid) to ChartBrowser but still working as expected. So I'm stuck with problem. The only thing I can do is preventing pane to resize smaller than certain width/height...  Here is problem: When resizing ChartControl (chartStyle: Bar, Bubbles, Spline etc etc, I guess all Diagram2D charts) and content is about to disappear because it's too small, processor is very busy and resizing gets very slow. It only happens when width of Value axes is zero. If someone encountered this problem as well, please reply in here.

Hi,

Aaron, we are reading them, just don't always have time to reply.  Post is sticky now.  Oleg just meant if you want an updated beta OCX you need issuetrack,

I'll answer a few now.

To start, any bug you found WILL be addressed for the next release, so I won't comment individually on them.

4. We know about it and will have smart labels.
11. You need to get the color of the element, not the series.  Color for series is only valid if color each is false.
12. Yes.  I don't think it is possible to check in code the number of colors.
13. Use chart builder.  There is palette tab on left.  There you can edit\add to the palettes.
15. You can adjust the range of the axis and\or play with zoom.

            Diagram.AxisY.Range.ViewAutoRange = False
            Diagram.AxisY.Range.AutoRange = False

            Diagram.AxisY.Range.MaxValue = 1000
            Diagram.AxisY.Range.MinValue = -1000
            Diagram.AxisY.Range.ViewMaxValue = 250
            Diagram.AxisY.Range.ViewMinValue = -250

16. Don't see error on my end, but it makes no difference for a bubble label.  It don't have lines.  Maybe we will add for future.
17. Currently no.

18. you need set MinSize/MaxSize properties - valus will be propertional to them.

oleg wrote: 16. Yes it designed. What showLines should mean for Bubble style?

16. fixed for next release.

Hi All,

 

I'm not sure if this has already been asked but are there any plans for the ChartPro Control to support Markup for ToolTips, eg, for a graph point and its associated label.

 

Aaron wrote: oleg wrote: Hi, 18. See how it works -    first it check all bubbles and find minimum width and maximum width.  now it set size of minimum width to value you set for MinSize and bubble with maximum width to value you set to MaxSize.  all other become proportional to these 2. So if you have 2 bubbles only first will be always MinSize and second always MaxSize.   Hi Oleg,   That is what I expected. If you have 2 values like the image, it doesn't look OK, don't you think?   MinSize = 0.1 MaxSize = 1         So, having proportional bubbles, I have to calculate MinSize & MaxSize myself. If setting MinSize to 0.9  it kind of "looks" proportional...

Thanks Aaron, we logged all your issues and will update you as we get to them.  Currently we are finishing backstage.

oleg wrote: Hi, 21. Yes with Black style it looks better - Appearance can be created with designer with borders. 23. Now you can manually set LabelText property.

Hi Oleg,

All issues are important...

All you need to do is answer questions one by one, just begin with first unanswered issue and if it's solved, fixed, answered or whatever goto next issue, it isn't difficult, really  The only thing you need to read is topmost reply.
