How to modify the colormap and the isoline range.

• You can see the colormap with the button ``Show ColMap'' (bottom in the working window).
• Different colormaps are provided in the menu ``Colormap'' (working window). Choose a different one, then ``redraw''.
• To modify the number of colours of this colormap, choose a number in ``NbColours'' (working window) menu.
  Then press the button ``redraw'' (working window) to print the isovalues with the desired number of colours.
• To modify the scale of the colormap, push on the ``SetIsos'' (working window) button. A window appears: ( see figure 1.39).

  Figure 1.39: Set scales of the colormap.

  

• You can modify the ``value range'' by changing the minimum and maximum of the values represented in the left colormap (left drawing area).
• If you click on ``adjust'' all the other values will be adjusted.
• You can also modify the ``value tics''; they represent the colour areas. Modify the first value (the minimum), then change the increment between each value, and then change the last value (maximum). Push on the ``set'' button (figure 1.39) and then ``redraw'' (working window) the mesh.
• Modify also the ``lines tics''; they represent the isovalue lines by defintion of the minimum, the increment between each line, and maximum. Push on the ``set'' button(figure 1.39) and then ``redraw'' (working window) the mesh.
• You can choose a ``cyclic colour'' . If this toggle button is off: above the maximum of the values (defined in the ``value tics'') and under the minimum of the values, the maximum (minimum) colour is drawn.
  Otherwise if this toggle button is on: above the maximum of the values and under the minimum, colours are drawn in cyclical mode.
• You can choose ``cyclic lines'' (figure 1.39). If this toggle button is off: above the maximum of the lines (defined in the ``lines tics'') and under the minimum, lines are not drawn.
  Otherwise if this toggle button is on, lines are drawn above the maximum (under the minimum).
• If you want to save these value and line ranges in a file in order to use them again in other applications:
  name the file (default name: vigie_3d.isos) and push on the ``save'' button.
  Then ``restore'' allows to restore the value and line ranges saved in the named file.
• To go back to the initial ranges, push on the ``reset'' button (figure 1.39 or working window).
• You can leave the ``set Isos'' mode by pushing the ``quit'' button (SetIsos window).
