Could the ability to choose to which axis (horizontal or vertical) the lines from the series points are dropped to be selectable ? Currently there is a line drawn from each series point to both the horizontal and the vertical axis. The option to only draw to either of them could be useful. Also, abi...

When Bar 3D series has its Bar Width is set to 100 % and is set to Self Stack, all bars except one appear to shrink to one pixel wide. Try this with the Chart Editor. Use Color Each to see each bar easier. Also, the specified Bar Width (say 50%) appears to occupy much less than 50% of the available ...

Whem\n makrs are visible, could the plot be shifted so that in the Y-direction, the entire mark (its label and its arrow) lie within the axis region ? Currently, the plot is shifted so that the mark arrow lies within the axis region but the mark label is outside the axis region. It can be clipped in...

Horizontal line series with Marks incorrectly shifts where the data is plotted within the axis region when the Botom axis is Inverted. This can be seen in the chart editor. Toggle the Bottom Axis Inverted checkbox property. When not inverted, the botom axis minimum lies at the left exis edge. The bo...

Could two other gradient directions be added that begin from Center ? Instead of going outwards both horizontally and vertically, could one only go horizontally and the other only vertically ? Sort of like combining the Left-Right with Right-Left (for horizontal only) and combining Top-Bottom with B...

Could an OnDragMark event be added to the DragMarks tool ? A separate event each for when the Mark is being actively dragged (mouse is down) and another event that fires only when the Mark drag completes (when the user releases the mouse button). The event should pass the index of which mark is bein...

Narcis, Are you moving the mouse on the chart to X=8 so the cursor gets positioned there, then moving the mouse vertically off the chart so the cursor remains at X=8. Then click the buton to programmatically change the XValue=1. Then move the mouse (still off the chart) so it is aligned above or bel...

A vertical Cursor Tool's OnSnapChange event does not fire if the cursor tool's X value has been changed programmatically and the next mouse movement is then back to the XValue the cursor tool was at before its XValue was changed. Fill a line series with 10 values (FillSampleValues) so its X axis goe...

With 2,000,000 points, about 1000 points are being plotted at each pixel. Have you tried the DownSampling function ? Or perhaps manually determine the number of points plotted per pixel and go through each sub-section of such plotted data and determine the local min and max and only plot that. I'm s...

Narcis,

This would show 2.5 as 2. Then, the axis value of 2.0 also appears as 2 and so two axis labels with the same text appear. I do not want any label shown for decimal labels, but I do want the tick mark. Things are working by specifying a space character instead of empty string.

Setting LabelText := '' in a chart's OnGetAxisLabel event causes axis labels to not be displayed in some cases. If this is done as a result of checking whether the label is a floating point number, then axis labels are not shown. For example : for i := 0 to 5 do series1.AddXY(i,random(10)); and then...

Is there any way to stop a chart zoom from updating its canvas so the new chart will not be seen ? I would still need to use the OnZoom event to access the zoomed axis values. When a Bar3D series having a CustomBarWidth is zoomed, the bar widths no longer have the same proportion. They can be reassi...

Could an OnAllowZoom event be provided that would supply the pending new axis limits along with an AllowZoom boolean that could be used to prevent that zoom from occuring ? This would be useful for example for Bar3D series where a CustomBarWidth has been specified. Zooming its chart causes the size ...

Narcis, Setting YOrigin for the series basically means having to set the minimum value for the series. Typically, one does not have to set the series minimum. The chart does that automatically by itself. It just seemed to me that there could be consistant behavior if the Bar3D series could also dete...

Bar3DSeries.UseYOrigin := false causes all bars to be drawn with their individual minimums set to the overall minimum of all bars. This causes all bars to be drawn down to the bottom axis. They no longer span just the range from their Y to Offset values. The Y axis minimum becomes the overall minimu...
