How can I combine a line plot and a bar graph into one figure?

Hello everyone, I have a data set of shares returns and shares turnover for a set of dates and for different shares that I was able to divide into subgroups that I need to plot as follow with the dates represented in the X axis and two Y axis for the following graphed data:

• The shares returns as a line plot
• The shares turnover as a bar plot

To do so, I created the given function:

function myplot(abtur,abret,date)
figure;
hold on
plot(date,abret);
hold on
bar(date,abtur);
hold off
end

And I use it as follow:

Work = readtable('Data Plotting.xlsx');

Work.Groups = findgroups(Work.Numero);

splitapply(@myplot,Work.AbnormalTurnover,Work.MarketAdjustedModel,Work.Date,Work.Groups);

However, It seems like my formula doesn't work as it provides me with the graph I did insert, can anyone please help me solve this matter?

Thank you a lot !

Can you attach your data? Your figure looks like a combination of a line plot and a bar graph, so what exactly is your question?

Hello Rik, I am trying to achieve the following figure from the set of data attached:

You should convert your date to an actual date format, either datetime or datenum. That should already help. Looking at the raw data you can also notice the adjusted data is fairly small compared to the other dataset.

If you want more explicit help, put your data in a mat file and attach it.

Thank you A LOT Rik ! That was really helpfull as it allowed me to have a better understanding of the data !

Hi,

Have a look at the following Matlab example. From my understanding of your question, the yyaxis function should be able to do exactly what you are looking for when it is used with the bar and the plot functions as shown in the example.
