Plotting a Gantt Chart from a Matrix

Hello,

I plotted this gantt chart in excel using this table.

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!
