9.5.1.4 The (Plot Details) Display Tab for Heatmap

PD-Dialog-Display4-Tab

This tab can be used to control the fill color, display styles, X/Y Coordinates and cell spacing between cells in a Heatmap/Polar Heatmap diagram created from worksheet data and matrix data both.

Fill Color

Specify how to fill the color for cells. There are three color options: Indexing, Direct RGB and Map.

By default, Map:Mat(#):"###" is selected and Colormap tab will show up as following tab to let you control fill color, cell border, etc.

If you choose Indexing or Direct RGB, Colormap tab will not show up, but a Border and Transparency control will appear to let you customize the cell border and transparency of the fill color.

Fill Display

It supports Square, Upper Triangular, Upper Triangular without diagonal, Lower Triangular and Lower Triangular without diagonal five display styles. This control is not available for a Polar Heatmap.

Gap between Cells

This control group can be used to adjust the gap between cells. It is not available for a Polar Heatmap.

Besides adding a gap after every cell(except the last cell) on X/Y direction, you are also allowed to add gap after every N cells, Nth cell and cells specified by column or label row(only for X direction).

About how the selections under the drop-down list work, you can refer to the examples below:

The X Direction and Y Direction slider are used to control the width of the spacing on X/Y direction, on a scale from 0 to 100. The Auto check box after Y's Gap slider is used to set each Y direction gap to be same as X's.

• When gap shows after every cell:
  • If the gap only in one direction:

    0 means there are no spacing between the cells in that direction, 100 means the cells will be displayed as lines in that direction.

  • If the gaps in both direction:

    The calculation method of gap value is different from above. The cell value is not independent for X or Y. In both two direction, 100% cell value=(cell width+cell height)/2.

    For example, if you set X Direction=30, Y Direction=50; the actual X direction gap value is set to (cell width+cell height)/2*30% and the actual Y direction gap value is set to (cell width+cell height)/2*50%.

• When gap shows for specified cell, not every cell:

  The unit of gap is % of data scale. For example, in X direction if there are 3 gaps and scale range of x is 1~200, then setting gap to 5% means each gap is set to (200-1+1)*5%/(3+1)=2.5 in x scale.

XY Coordinates Mapping on Matrix

The option is usually used for the Heatmap plotted by NetCDF data, to set the longitude and latitude.

• X/Y Coordinates

Support to set X/Y coordinates from matrix.

• Orientation

Specify the orientation to Arbitrary, Clockwise or Counter Clockwise.
