How to draw an axis

How to draw the red axis on a graph？
Using c++builder。

Hello,
you can do this by using the ColorLine Tool (two, one for vertical and another one for horizontal).
You can find an example of use of the ColorLine tool in the TeeNew examples features included with the installation.

Please, do not hesitate to contact us in the case we can be of a further help.

I can't find it. Can you give me a demo？

Hello,

you can use the following code to add a colorline tool and then customize it.

Code: Select all

//Now add colorlinetool outside the min/max range of the data
TColorLineTool *line = new TColorLineTool(TrendChart);
TrendChart->Tools->Add(line);
line->AllowDrag = false;
line->NoLimitDrag = false;
line->Axis = axisVert;
line->Pen->Color = clBlue;
line->Pen->Width = 2;
line->Value = 32;

Please, let us know in the case any help still needed.

line->Axis = axisVert;
What is axisVert???

Hello,
axisVert was used in the case you want to make use of a new custom axis, like:

Code: Select all

//Add vertical axis
TChartAxis *axisVert = new TChartAxis(TrendChart);

axisVert->Maximum = dblMax + 1;
axisVert->Minimum = dblMin - 1;
axisVert->Grid->Visible = true;
axisVert->Automatic = false;
axisVert->AutomaticMinimum = false;
axisVert->AutomaticMaximum = false;
axisVert->PositionPercent = 0;
axisVert->Horizontal = false;
axisVert->OtherSide = false;
axisVert->Visible = true;
axisVert->LabelsFont->Color = clRed;

but you can always use instead:

Code: Select all

Chart->Axes->left
