Change log for latest version

Where do I find the changelog for the latest TChart update? I would like to see it before I download and install it.

Thank you,

Re: Top/Bottom line in a chart

Thank you. That works perfect for the TChart, but when I create an image of the chart with a different width, the lines are not the correct width. See the attached demo--the red lines are painted in the AfterDraw event and are not the correct width.

Top/Bottom line in a chart

I have a horizontal bar series in a chart. A customer wants the axis line on the bottom of the chart to extend farther left, and one at the top that matches. See here: http://www.tbinc.com/misc/ChartExtendHorzLineLeft.jpg I put arrows showing the lines. Is something like this possible? (I have attac...

Re: Keeping the Legend Symbols the same size

I posted this in the wrong group, but in case you are wondering, here is the solution: procedure TForm1.ChartLegendDraw(Sender: TObject; aSeries:TChartSeries; aValueIndex:Integer; aR:TRect); var lCanvas: TCanvas3D; lClr: TColor; begin lCanvas := aSeries.ParentChart.Canvas; lClr := aSeries.LegendItem...

Re: Keeping the Legend Symbols the same size

I tried the following code but it colors each symbol with the same color (of course). I don't know how to get the color for each slice. Chart1.Legend.Symbol.OnDraw := ChartLegendDraw; procedure TForm1.ChartLegendDraw(Sender: TObject; aSeries:TChartSeries; ValueIndex:Integer; R:TRect); var lBarSeries...

Keeping the Legend Symbols the same size

In the attached demo, you can select if the line for the pie series is visible or not, and if it is, if it is white or black. THis part works fine. I would like to keep the symbols in the legend large--without the border around them (like the chart when no series pen is visible). Can this be done? T...

Re: Labels for horizontal series

That's cool... but I don't know how you did that--attached is my demo that neither right aligns the values not bolds the items.

What am I doing wrong?

Labels for horizontal series

Attached is a simple demo where the horizontal series caption has two lines. Works fine. My customer wants two modifications that I do not know how to do: 1) They would like the left axis labels to be right-aligned. 2) They would the second line (the value) bolded. Are either of those possible? Than...

Horz labels dropping

I have a horizontal bar series with two-line labels in the axis--but if there is too much data, then the labels can get dropped. (Se http://www.tbinc.com/misc/ChartHorzLabels.jpg Two questions: 1) What setting is the margin between the labels? It seems a bit to aggressive here. 2) Is there a way of ...
