Is there a way to visualize the effect of a filter on a signal while designing the filter?

Hi! I was trying to use Filter Builder and was wondering if there was a way to have it display the effect of the filter on a vector of data. I want to bring in the data, select different filters and then watch the filtered data change as I change the filter so I can experiment with different filters and find one that works best with my data. Could you please let me know if this is possible? Thanks in advance!

Hi,
As mentioned in the following documentation page:
"When you have achieved the desired filter response through design iterations and analysis using the Filter Visualization Tool, apply the filter to the input data. Again, this step is never automatically performed for you by the software. To filter your data, you must explicitly execute this step."
One workaround to visualize the effect of a filter on a signal while designing the filter, is to design a GUI which uses 'filterbuilder'.
I have attached a sample GUI app 'FilterDesign.m' and 'FilterDesign.fig', which imports data from 'SampleData.mat' file, then the filter can be designed using Filter Builder app, and then plots the filtered data. The filter name I have used is 'Hlp' and can be changed in the 'FilterDesign.m' file to your own filter name.
