HOWTO add menu items:
Warning: this is a complex multistep process!
1. Edit TPlot.wb1 and add the menu item(s) you want.
It is best to add them in their correct position near rows 209-269.
Add its hint similarly, in the rows below.
Make sure you update the indices correctly.
2. Open Images32.res in the Image Editor.
3. for i := MaxImageNo downto NewIndex do
ImageIndex := ImageIndex + NoNewMenuItems;
4. create your new 16x16x256 bitmap(s), and rename them to NewIndex, ....
5. Save Images32.Res.
6. Open Plotxxx_xx.bpg, open Plotxxx_Rxx.dpk, and ...
7. In Plotdefs.pas, insert your new mnuMyNewMenuItem(s).
8. In PlotImageList.pas, redefine NO_IMAGES to the new value.
9. In Plot.pas, create your new MyNewMenuClick method(s).
10. In Plot.pas, go to the CreateOnClicks procedure of TCustomPlot.CreateMenus, and add:
FPlotPopUpMenu.Items[Ord(mnuXXX)].Items[Ord(mnuMyNewMenuItem)].OnClick := MyNewMenuClick;
11. Similarly add the Caption and Hint.
20. Change
TPlot.DetermineMenuVisibility,
TPlot.SetSeriesVisibility and
TPlot.SetSeriesEnabledness
TPopupOptions.Create
as required.
21. If you are support languages than English, try to translate your new menu caption and hint.
22. Export the neccessary resourcestrings from the spreadsheet to the TPlot/lang/eng.txt (and other) files.

pMenuArray = ^TMenuArray;
TDegrees = 0..359;
TDirection = (drHorizontal, drVertical);
{Screen objects are often Horizontal or Vertical.}
TOrientation = (orRight, orLeft);
{Other screen objects can be Left or Right aligned.}
{Different possible plot types: these determine how the series are interpreted,
and so how data are displayed on screen}
TPlotType = (
ptXY,
ptError,
ptMultiple,
ptBubble,
ptColumn,
ptStack,
ptNormStack,
ptPie,
ptPolar,
ptLineContour,
ptContour,
pt3DContour,
pt3DWire,
pt3DColumn);
{ptXY - a normal XY plot that everyone does in sigh school
ptError - every second (odd indexed) series is interpreted as the "error bar" of the
previous (even indexed) series.
ptMultiple - each "point" is composed of a multiple of points from
the different series. This is a generalised extension of the previous
ptError type. It is used for High-Low-Close, High-Low-Open-Close, etc
plots. Eg:
high, low high, average, low high, low, open, close;
X X H
| | |
| | O
| O |
| | |
| | |
| | |
| | C
| | |
X X L
See the Multiplicity property !
ptColumn - columns of data: the last X value is taken as Xn + (Xn - Xn-1),
so the appearance is:
(X1, Y1)----(X2, Y1)
| |
| (Xn, Yn)----(Xn+dX, Yn)
(X0, Y0)----(X1, Y0) | |
| | | |
| | | |
| | | |
| | | |
(X0, 0)---------(X1, 0)------------(X2, 0)---------(Xn+dX, 0)
- when there are N (> 1) series, each gap is divided by (N+1):
-------
| |
| |
------- | |
| |------ | |
| | | | |------
| | | | | |
| | | | | |
(X0, 0)---------(X1, 0)------------(X2, 0)
ptStack - a stacked column, with each series on to of each other
ptNormStack - like a stack, but normalized to 100%
ptPie - very boring pie graphs
ptPolar - (x, y) = (r*cos(theta), r*sin(theta))
ptContour - a two-dimensional plot where the color represents the Y value.
pt3DContour - a three-dimensional plot where the color represents the Y value.
pt3DWire - a three-dimensional plot in which each series in order as succesive slices through the surface
