color problem with Time Series Add-on #139

Closed rodrigocns closed 2 years ago

rodrigocns commented 4 years ago
Timeseries version

0.3.7

Orange version

3.26.0

Expected behavior

When changing lines of various plots in the Line Plot Widget, the colors should follow a order (blue, red, green, etc.)

Actual behavior

When changing lines of various plots in the Line Plot Widget, the colors actually keep progressing through the color sequence, as if the changed line was a different one.

Steps to reproduce the behavior

From a temporal data table with a couple of columns (A,B,C,D,E,F) Add 2 or more plots to a Line Chart Widget. Select the data of each one (A B in first plot, C D in second plot). Change one of the lines some times (D to E, to F, to D again, to A, to D, etc). Each change makes the color keep changing, with the same number of lines.

Bonus: if I change the data table to a diferent one with similar data (Aa, Ba, Ca, Da, Ea, Fa), all lines get new colors, and now it is much harder to see the data.

Additional info (worksheets, data, screenshots, ...)

1st: all fine. 2nd: changing line color. 3rd: changed sheet, color hell. https://drive.google.com/file/d/1fcl0pdcUh_yOEnofQKOwgskElHdFX5_u/view?usp=sharing https://drive.google.com/file/d/1JBI6wqVqrhJRebYhH0prXOyX9sdS5nTH/view?usp=sharing https://drive.google.com/file/d/1VxBwHrsF6VT6TiIpRhRxbBlMQ6UoeWoF/view?usp=sharing

The solution might be to set a fixed line color here: https://github.com/biolab/orange3-timeseries/blob/f4f7934f6cc55774342cce46ad2f1fef7c692cfd/orangecontrib/timeseries/widgets/owlinechart.py#L246-L250

This will also be fixed as a part of #56.
