Plotting in app designer

I am creating an app to quickly plot csv data. UiAxis for plot needs to be updated once the data is imported but I cannot get it working. The UIAxis element is done in app designer. Plotting is done with app's internal function:
methods (Access = private)
function results = plotWidths(app)
histogram(app.UIAxes, app.Data.Width)
end
The plot component (named UIAxes) is within a panel if that makes any difference. The property Data is a table that has a column Width.
Thank you already in advanced.

So basically, you want to upload some numerical data from your excel file and plot it on App Designer?

From what I can tell, your version should be working. I tested the following:
The structure of the components:
app.UIFigure
app.Panel
app.UIAxes
test.csv:
Width, Height
1, 7
2, 6
3, 5
4, 4
5, 3
6, 2
7, 1
The function from where the .csv is read and the plotWidths function is called. I chose the startupFcn for ease of testing, but it could be any other method or callback.
function startupFcn(app)
filename = 'test.csv';
csv_table = readtable(filename);
app.Data = csv_table;
plotWidths(app);
end
The same plotWidths method that you used:
function results = plotWidths(app)
histogram(app.UIAxes, app.Data.Width)
end
When I run this with Matlab R2017b it works without any errors. Does your use deviate in any meaningful way from this?

The default value for UIAxes.XLimMode and UIAxes.YLimMode is 'auto', 'manual' would need to be set before plotting.
