GPL: reverse brightness into darkness

[Kirill Orlov]

GPL color.brightness allows to show values by rightness of a colour. For example,

ELEMENT: point(position(x*y), color.brightness(Z), color(color.grey))

shows points in grey, the brightness of the grey being defined by values of some variable Z. The greater is Z the lightgter is the colour.

I want to reverse it: the greater is Z the darker is the colour. This simple

ELEMENT: point(position(x*y), color.brightness(-Z), color(color.grey))
or
ELEMENT: point(position(x*y), color.brightness(eval(-Z)), color(color.grey))
does not work.

Can you help?

Please note that I cannot negate (or anyhow convert) the Z variable's values in the variable itself, in the dataset, prior the GGRAPH command, because I want the legend on the graph relate the original Z's values.

The Z parameter has a range 0..1, from darkest to brightest. If your data is
scaled to this range you can reverse it prior to invoking GGRAPH (revZ =
1-Z), or you could manually add a TRANS: revZ = eval(1-Z), and change all
occurences of Z to revZ in the following GPL code.

According to GPL Guide,

color.brightness(<algebra>)
or
color.brightness(color.brightness."brightness value")
or
color.brightness(<statistic function>)

<algebra> or <statistic function> needs not to be in the range 0-1, so Z
variable may have any numeric values.

The TRANS - that could be solution, perhaps.
I will wait for alternative solutions, if any.

Thank you.

I think all values going into the brightness value are scaled into the 0..1
range. Empirically looks that way...
In the case of reversal you will have to reverse the scale with MAX(Z) in
syntax as max() is not supported by eval() (I think).

You can just negate the brightness variable and leave it the brightness function for scaling

  TRANS: z = eval(-z)

I think that z can't be a categorical variable in the GPL code, however.

TRANS: neg_Z = eval(-Z)
does the job
but unfortunately the values displayed on the legend also negate. I have a legend.
Below is my example with a heatmap.

The problem left with the second one is that the LEGEND corresponds now to VAL2, but I want it to correspond to VAL (i.e. the darkmost must be 1.0, not -1.0)

You can just negate the brightness variable and leave it the brightness function for scaling

  TRANS: z = eval(-z)

I think that z can't be a categorical variable in the GPL code, however.

How about this.

GGRAPH /GRAPHDATASET NAME= 'graphdataset' VARIABLES= col row val /GRAPHSPEC SOURCE= INLINE.

BEGIN GPL

  PAGE: begin(scale(700px,520px))

  SOURCE: s=userSource(id("graphdataset"))

  DATA: col=col(source(s),name("col"),unit.category())

  DATA: val=col(source(s),name("val"))

  TRANS: val2=eval(-val)

  GUIDE: axis(dim(1),label(" "))

  GUIDE: axis(dim(2),label(" "))

  GUIDE: legend(aesthetic(aesthetic.color.brightness.exterior),null())

  SCALE: cat(dim(1),sort.data())

  SCALE: cat(dim(2),sort.data(),reverse())

  ELEMENT: polygon(position(col*row)),color(color.grey),color.brightness.exterior(val2),color.brightness.interior(val2))

does the job
but unfortunately the values displayed on the legend also negate. I have a legend.
Below is my example with a heatmap.

The problem left with the second one is that the LEGEND corresponds now to VAL2, but I want it to correspond to VAL (i.e. the darkmost must be 1.0, not -1.0)

You can just negate the brightness variable and leave it the brightness function for scaling

  TRANS: z = eval(-z)

I think that z can't be a categorical variable in the GPL code, however.

This looks better but does not solve the problem. The values' scale at the legend goes according to val2, and I want it to be mirrored (be according to val).

does the job
but unfortunately the values displayed on the legend also negate. I have a legend.
Below is my example with a heatmap.

The problem left with the second one is that the LEGEND corresponds now to VAL2, but I want it to correspond to VAL (i.e. the darkmost must be 1.0, not -1.0)

You can just negate the brightness variable and leave it the brightness function for scaling

  TRANS: z = eval(-z)

I think that z can't be a categorical variable in the GPL code, however.

I believe

SCALE: linear(aesthetic(aesthetic.color.brightness), reverse())

does what you want Kirill. Via Progman's earlier example:

X Y Z (2F8.0 F8.2).
BEGIN DATA
1 1 0.00
2 1 0.25
3 1 0.50
4 1 0.75
5 1 1.00
END DATA.
EXECUTE.

*No reverse, original scale.

For your actual example Kirill you need to also do interior/exterior. But
this works generally for all 'aesthetic' scales, so works for colors, sizes,
etc.

This is great Andy. It is what I wanted.
And it doesn't need TRANS statement, which is better.
Thank you.
