TMS FNC Chart 4.0 BETA

Intro

We are excited to announce TMS FNC Chart 4.0 BETA! This beta brings a more flexible layout model and smarter label handling while keeping the familiar TMS FNC Chart API intact. It is a focused update aimed at making charts easier to read, easier to style, and easier to fit into modern UI layouts.

What's New in 4.0

• Horizontal mode: render charts with a horizontal orientation using the new Orientation property.

• Smart Labels: improved label behavior for XValues and YValues to keep axis labels clearer and more readable.

Using Horizontal Orientation

Switching between vertical and horizontal layouts is a single property change. Use TTMSFNCChartOrientation with values coVertical (default) and coHorizontal.

TMSFNCChart1.Orientation := coHorizontal;  // Switch to horizontal layout

To restore the classic layout:

TMSFNCChart1.Orientation := coVertical;    // Default vertical layout

Smart Labels in Action

Smart Labels give you better control over how axis labels are spaced and rotated. You can enable the behavior per series and fine tune label density with MinLabelSpacing, MinLabels, and MaxLabels. When AutoRotate is enabled, labels can rotate automatically to avoid collisions.

with TMSFNCChart1.Series[0].XValues.SmartLabels do
begin
  Enabled := True;
  AutoRotate := True;
  MinLabelSpacing := 8;
  MinLabels := 3;
  MaxLabels := 10;
end;

You can apply the same configuration to the Y axis when needed:

with TMSFNCChart1.Series[0].YValues.SmartLabels do
begin
  Enabled := True;
  AutoRotate := True;
  MinLabelSpacing := 6;
  MinLabels := 3;
  MaxLabels := 8;
end;
