Hi, Does anyone know how to extend the curve fitting line on the toolbox?
I have attached an image, and essentially i would like it to reach 5x10^4.
Cheers

That's the generated code
function createaxes(Parent1, XData1, YData1, XData2, YData2)
%CREATEAXES(Parent1, XData1, YData1, XData2, YData2)
% PARENT1: axes parent
% XDATA1: line xdata
% YDATA1: line ydata
% XDATA2: line xdata
% YDATA2: line ydata
% Auto-generated by MATLAB on 21-Oct-2018 12:43:47
% Create axes
axes1 = axes('Parent',Parent1,'Tag','sftool surface axes');
hold(axes1,'on');
% Create line
line(XData1,YData1,'Parent',axes1,'DisplayName','Dmge vs. flow1',...
'MarkerFaceColor',[0 0 0],...
'MarkerEdgeColor',[0 0 0],...
'MarkerSize',3,...
'Marker','o',...
'LineStyle','none');
% Create line
line(XData2,YData2,'Parent',axes1,'DisplayName','untitled fit 1',...
'LineWidth',1.5,...
'Color',[0.0705882352941176 0.407843137254902 0.701960784313725]);
% Create zlabel
zlabel('Z');
% Create ylabel
ylabel('Damage ($000 USD)');
% Create xlabel
xlabel('Flow A');
% Create title
title('Damage vs Flow A');
% Uncomment the following line to preserve the X-limits of the axes
% xlim(axes1,[-1259 50000]);
% Uncomment the following line to preserve the Y-limits of the axes
% ylim(axes1,[-1136 24374]);
% Uncomment the following line to preserve the Z-limits of the axes
% zlim(axes1,[-1 1]);
box(axes1,'on');
grid(axes1,'on');
% Set the remaining axes properties
set(axes1,'FontSize',14,'FontWeight','bold');

I didn't write a code. I just used the curve fitting tool box on MATLAB.
I am not really concerned with the quality of the fit, rather I would like the line of fit to not stop where the data is, but to go on onto the end of the x-axis.
