4.15.3 False Color Maps
In the Color vs. Time and the False Color plot, color values or gray-scale intensities are assigned
to parameter values.
The colors are chosen from a Color Map. The following pre-set color maps are available: Jet, Hot,
Cool, Gray and Jet reverse. Each color map consists of 64 different colors arranged
in a particular way.
The range of the y-axis (defined in the display) is assigned to the selected Color Map, that is, the
leftmost color corresponds to the minimum y-value (Min) , and the rightmost color corresponds
to the maximum y-value (Max). The interval between min and max is straight-proportional to the
colors in-between. For example, low values can be displayed in cool colors, and high values in
warm colors (false color map Jet). Or you can display low values in dark gray scales, and high
values in light gray scales (Gray).
The color of the actual value is looked up from the Color Map accordingly. Parameter values
outside the defined min/max range are plotted in Black.
Example: If the range was set from min = 0 Hz to max = 64 Hz, each color of the map would
correspond to 1 Hz steps. Spike rates lower than 1 Hz would then be plotted as the first (leftmost)
color of the color map, spike rates between 1 Hz and 2 Hz would be plotted as the second color
of the color map, and so on. A value above 64 Hz would be plotted in black.
4.15.4 False Color vs. Time (Plot)
In a Color versus Time plot, color values or gray-scale intensities are assigned to parameter
values. This feature can be used to enhance the visibility of details in the plot. You can choose
between four different false color maps.
The Color vs. Time plot shows the data as colored vertical bars over time. Each y-value
is assigned to one of 64 colors (defined by the Color Map).
Note: Only one input data stream can be displayed here.
4.15.5 False Color Plot
In a False Color plot, color values or gray-scale intensities are assigned to parameter values.
This plot type is very useful for two-dimensional applications. It gives you a good imagination
of different areas of activity in your preparation.
