The 3D Chart
Editor
There is a 3D chart editor
for the
lego chart
and one for the surface
chart.
The surface chart editor
contains a subset of the fields of the lego chart editor (is missing
the fields Draw Blocks, Lines While
Animating and
Sparsify Threshold, which don't make sense for a
surface).
Therefore the lego editor will be described.
2D
charts use
vectors (1-dimensional matrices) to populate their series, 3D charts
use pure 2-dimensional matrices; vectors are not allowed. There is
only one series in a 3D charts, which is equivalent to a matrix.
But let's give a
look to the editor.
The Settings panel
In
the Settings
panel of the editor you specify:
- The
names of the 3 axes of the chart. These names are displayed as axes
labels in the chart.
- The option Log
Z
Scaling. If not checked, only the extreme values of the Z
axis are displayed on the Z axis. If checked, also some middle values
are displayed.
- The option Draw Blocks.
If checked the lego blocks (like the bars in the 2d bar charts) are
displayed. If not checked, only some lines are displayed.
- The
option Lines While
Animating. If checked the lego blocks are substituted by
lines when you are turning or moving the 3d chart.
- The
option Sparsify
Threshold. It is “ a limit on the number of bins
that should be drawn when animating plot” (from FreeHep).
Which means that if you rotate or move the 3d chart the number of items
that are displayed (lego bars or lines) is not bigger that this
threshold.
The Values panel
In
the Values
panel of the editor:
- in the Values
field you choose the matrix to display using the matrix selection
dialog that appears clicking on the ...
button.
- In the
Interval X panel you specify the interval of the x
axis in which the columns of the matrix (x-dimension) are equally
distributed.
- In the Interval Y
panel you specify the interval of the y axis in which the rows of the
matrix (y-dimension) are equally distributed.
