I am a newbie of originlab.
How to mask some lines in a parallel plot?
In my workbook, there is a column including categorical value, "pass": 0 or 1.
I want to mask lines for data [ data["pass"] == 0 ] with grey color, while lines for data [ data["pass"] == 1 ] are colored with blue-red colormap.
Below is current state and I want to colormap lines with "pass"==0 grey.
Below is a similar style. pass==0 lines are colored grey:
Here are the similar figures: https://github.com/plotly/plotly.js/issues/2756 |

Hi,
Do you mean for data["pass"] == 1, you want to colormap to another column, for example column species_id? In such case, you need to
1. add another column, right click to open set column value.
2. fill dialog with IF(Col("pass")==0, 0, Col("species_id")), and OK
3. set line color map to this new column
4. in Colormap tab, set level to 1~3, set color fill for level<1 to grey.
Thanks
Cecilia |

Sorry. I re-wrote it more clearly.
I want to make figure like above. But, I want to color some lines that "pass" ==0 as grey to emphasize "pass"==1 lines. And, I don't want to change the lines that "pass" == 1 (current Blue-red palette like above).
Please note that the column "path" is categorical variable; 0 or 1.
Thank you. |

Hello,
You can add a new column and set F(x) cell with if() function.
E.g. my Pass column is E. My colormap value is in F.
I can add if(E=="1",F, -1) in the F(x) formula in G column so if Pass=1, return F value. If Pass=0, return -1 (some value outside the colormap range).
Then on Colormap tab of Plot Details, map -1 with gray.
Thanks, Snow

Thank you for your help. It was so helpful!
*And also thanks to Cecilia. Now I understand what you mean. It was the same answer. Thank you!
