The Chart Tree
Add
a chart
You can view matrices graphically
using charts.
To add a chart, click on the Charts
tree view in the project toolbox with the right button of the mouse.
In the pop up menu select New chart.
A
sub-menu
appears, with
several choices:
We
have three groups of charts:
- pie charts, which can display one 2D series.
- multi-series charts
(category, xy, time). They are called like that because each chart can
display multiple series (multiple matrices).
- high-low charts, which displays 4 or 5 series (high, low, open, close, volume).
- 3d charts (lego3d,
surface3d), which can display one 3D series.
The multi-series chart can display series of
these types:
- line
- line
3D
- bar
- bar 3D (only the
category chart)
- area
- scattered
- scattered
line.
The series type is decided when adding a new series to the chart in the multi-series chart editor.
Let's give a close look at each single chart type:- pie
charts (JFreeChart, only one series per chart):
- Category
chart (JFreeChart, multiple series per chart), where each y value of
each series is related to a label on the x
axis:
- XY,
in which each element of the series is an <x,y> point.
The x sequence is not necessarily linear and regular (1,2,3...), so the
line chart can have a zig-zag pattern, like in the first example:
- Time,
in which the x axis is a time axis:
- HighLow, that show 4 or 5 values at the same time (high, low, open, close, volume) on a time axis:
- Lego3D, which is a 3D bar chart:
- Surface3D, which represents the values using a 3D function representation:
Selecting
the chart to add in the menu, the chart editor for that
kind of chart opens.
