Output of histfit without the plot

Is there a way to get the fitted curve generated by histfit without it being plotted? I want the curve it generates, but I don't want the plot it generates. Thanks times a million in advance.

Try this:

r = normrnd(10,1,100,1);                                % Create Data
h = histfit(r,6);
set(gcf,'Visible','off')
CurveX = h(2).XData;
CurveY = h(2).YData;

I thought about doing something like that, but I would prefer to not have to have any graphics generated. I came across fitdist, so I ended up doing something like the following:

x = (-6:0.1:6);
r = randn(1024,1);
pd = fitdist(r, 'Normal');
pdr = pdf(pd, x);
% See the fit
figure
histogram(r,'Normalization','pdf');
hold on; grid on;
plot(x,pdr,'LineWidth',2)

Thanks for your response!

My pleasure!

In my code, none of the graphics are visible. A slightly different version is:

r = normrnd(10,1,100,1);                                % Create Data
figure
set(gcf,'Visible','off')
h = histfit(r,6);
CurveX = h(2).XData;
CurveY = h(2).YData;

I thought of using fitdist and pdf, however since histfit is what you specified, does everything in one call, and you didn’t mention wanting the parameters, I decided to go with that.

I did not know about fitdist when I asked my question. I came across that later, but before I saw your first response. As it turns out, I did want to plot the fit, so using histfit and grabbing the data like you show above would've done what I wanted!! Anyway, I now know two solutions, and there's nothing wrong with that!!

Thanks again!!

Hi,

I am wondeirng if there is a way to only plot the fit but not the histogram, using histfit?

Thanks

[Star Strider]

@Charlotte Han — There is.

Two options —

figure
hhf = histfit(2*randn(1,100)+1, 25);
Bars = findobj(hhf, 'Type','Bar');
delete(Bars)                                            % Delete 'Bar' Plot

Lines = findobj(hhf, 'Type','Line');

figure
plot(Lines.XData, Lines.YData, '-r', 'LineWidth',2)     % Save & Plot 'Line'

.

[Charlotte Han]

Much appreciated!

Am I able to have two fits on the same plot but not on top of each other, but side by side like subplots?

[Star Strider]

I am not certain what you want to do. See if the tiledlayout function will work.

A Vote would be appreciated!

r = normrnd(10,1,100,1); % Create Data

h = histfit(r,6);

set(gcf,'Visible','off')

CurveX = h(2).XData;

CurveY = h(2).YData;
