# Update plot uitable problem

hey, I'm a Matlab beginner and I need help...
I've got a 2x2 table to define an area. I've created a ui within my function just to show the table and plot the area. this is how far I am right now. what's left is that I'd like the plot to update when the values in the table change. the values are editable but the plot remains the same.
any help is appreciated!!
t = table(Drehzahl, Drehmoment, 'RowNames',{'Startpunkt' 'P1' 'P2' 'P3' 'Endpunkt'});
fig = uifigure;
fig.Position(3:4) = [822 360];
uit = uitable(fig,'ColumnEditable',true);
uit.Data = t;
uit.FontSize = 10;
uit.FontWeight = 'bold';
uit.ColumnEditable = true;
uit.Position(3) = 375;
ax = uiaxes(fig);
ax.Position(1) = 415;
ax.YLabel.String = 'Drehmoment [Nm]';
ax.XLabel.String = 'Drehzahl [rpm]';
x = t{:,1};
y = t{:,2};
area(ax,x,y);
ax.XLim = [0 45];
ax.YLim = [0 2000];
ax.Title.String = 'Feld der gefahrenen Punkte'; Ankit on 10 Dec 2019
You can use DisplayDataChangedFcn callback but it is available in r2019. I have not seen it in 2018b or previous release.

After a while, I found a solution to this problem:
t = table(Drehzahl, Drehmoment, 'RowNames',{'Startpunkt' 'P1' 'P2' 'P3' 'Endpunkt'});
fig = uifigure;
fig.Position(3:4) = [822 360];
uit = uitable(fig,'ColumnEditable',true);
uit.Data = t;
uit.FontSize = 10;
uit.FontWeight = 'bold';
uit.ColumnEditable = true;
uit.Position(3) = 375;
uit.CellEditCallback = @updateFigure;
ax = uiaxes(fig);
ax.Position(1) = 415;
ax.YLabel.String = 'Drehmoment [Nm]';
ax.XLabel.String = 'Drehzahl [rpm]';
x = t{:,1};
y = t{:,2};
area(ax,x,y);
ax.XLim = [0 45];
ax.YLim = [0 2000];
ax.Title.String = 'Feld der gefahrenen Punkte';
function updateFigure(src,event)
x = uit.Data(:,1);
y = uit.Data(:,2);
area(ax,x,y)
end

that worked perfectly, thank you so much!
do you know, how the new edited values can be stored in a vector??

R2018b
