Hi.

Thanks for reporting this one. The TCustomBoxPlot series does not yet implement Clicked method. We'll try to improve this in future.

Hi, Aaron. Settinng the TreatNulls property to Steema.TeeChart.Styles.TreatNullsStyle.DoNotPaint does what exactly what IgnoreNulls = false; did in old version. When TreatNulls is set to DoNotPaint, then the null points (points with color = Color.Transparent) will be skipped and the chart will have ...

Hi, Lars.

The internal calculations (median, percentiles) assume ordered values i.e. you must order the values before you add them to box series.

In this case all you must do is type cast Series class to Line class (if it can be done). Something like this:

Code: Select all

if (tChart1.Series[index] is Steema.TeeChart.Styles.Line)
  (tChart1.Series[index] as Steema.TeeChart.Styles.Line).LinePen.Width = 2;

Hi.

I think in this case the easiest solution is to use area series with it's Stairs property set to true:

Code: Select all

area1.Stairs := True;
area1.AddXY(1,10);
area1.AddXY(2,3);
area1.AddXY(3,5);
area1.AddXY(4,7);
area1.AddXY(5,7); // add fake point to show last bin

Hi, CAC. ValueIndex = point index in series point ValueList array. In your case I assume the number of points is equal to number of points in ClinetDataSet. In this case ValueIndex would be equal to record position in ClientDataSet. If this is not true you can still create an array of bookmarks and ...

Hi.

To have a pdf image format listed in the export dialog at runtime, you have to add TeePDFCanvas unit to the Uses section:

Code: Select all

Uses ..., TeePDFCanvas;
This will automatically add "PDF" to export format list. The same rule applies to other export formats (VLM = TeeVMLCanvas, PNG = TeePNG, ...)

Hi.

Are you by any chance using the "Build with the runtime packages" option ? If yes, then perhaps the problem is your project is referencing old (TeeChart Standard) packages. In this case all you must do is replace references to old TeeChart bpi/lib files wih version you use.

Hi. This is because the reference to this.marksTip1 is set to null after you load the chart. After load you cannot reference marksTip1 anymore .. that is, unless you reassign the variable as: marksTip1 = tChart1.Tools[0] as MarksTip; or alternatively, in your code reference tChart1.Tools[index] and ...

Hi.

I think the two stars (*) represent two outliers (0.0156 and 0.03489) and not the minimum nd maximum value. Minimum value is still 0.0 and because it's not an outlier, it's not drawn. Only the (mild and extreme) outliers are drawn.

Hi. Sorry for the confusion, I mixed the VCL and .NET version. In .NET, you could use the Colors array to control individual point color. For example: int index = e.ValueIndex; // plot all positive values green, negative and zero red if (series.YValues[index] > 0) series.Colors[index] = Color.Green;...
