Plotting a Gantt Chart from a Matrix

Hello,
I plotted this gantt chart in excel using this table.
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/167454/image.jpeg)
The Gantt Chart looked like this

To remove the gaps durations, I used the legend to de-colored them, remove the boarders and remove them.

Now, I would like to plot the same gantt chart in Matlab using the following command:
barh(Positions,Gap_Duration,'stacked');
where:
Positions=[1,2,3,4];
Gap_Duration=[0,2,5,3,5,3;
3,5,3,5,3,4;
9,3,0,0,12,2;
13,2,2,2,8,3];
However, I want to change the color for every job duration (every even column at the Gap_Duration Matrix) and No-Color & No-Boarder for every gap duration (every odd column at the Gap_Duration Matrix).
Note: this only a simple example, I am dealing with a Gap_Duration Matrix with a size of (60,55*2),
60 positions and 55 jobs with their 55 gaps. where each job should have its own color or at least every 8-10 jobs have different color.
I already did the code for obtaining the Gap_Duration Matrix.
Thanks in advance.

Use graphic handles to manipulate the graph:
Positions=[1,2,3,4];
Gap_Duration=[0,2,5,3,5,3;
3,5,3,5,3,4;
9,3,0,0,12,2;
13,2,2,2,8,3];
H = barh(Positions,Gap_Duration,'stacked') ;
set(H([1 3 5]),'Visible','off')

Hello Jos,
I don't understand the following command. Could you explain me?
" set(H([1 3 5]),'Visible','off') "
Thanks In Advance ... :)

Whenever Matlab plots something it creates a handle to the plotted object. You can manipulate these objects by setting its properties using the handles. In the example above, H is a array of handles to bar elements (see the documentation of barh). The command sets the property "visible" to off for three of them.

If it helps, I just published a custom Gantt chart for anyone to use and download on File Exchange here: https://www.mathworks.com/matlabcentral/fileexchange/116970-gantt-chart?s_tid=srchtitle. If you have any questions or feedback, feel free to let me know!
