Is it possible to tell the matlab plot(fts)function not to display the gaps caused by weekends?

It is possible to plot financial data without weekends.
Please look at the example code. We use "set(gca…)" to tell the x axis which dates to plot.
datum=Aktie.dates(400:end); %These are the dates we want to plot. Normal Matlab datenumbers.
figure
hold on
candle(Aktie.high (400:end), Aktie.low (400:end), Aktie.close(400:end), Aktie.open(400:end), 'b') %Let's plot a candle chart.
plot(LONG(400:end), 'r'); %with a moving average
%This is the important date section
tick_index = 1:10:length(datum); % checks length of the dates with 10 steps in between.
tick_label = datestr(datum(tick_index), 6); % this is translated to a datestring.
%Now we tell the x axis to use the parameters set before.
set(gca,'XTick',tick_index);
set(gca,'XTickLabel',tick_label);
It should look like this:

make the gaps NaN and the plot will skip the NaN data.

What exactly do you mean by gaps? The plot should always interpolate linearly between the Friday and the next Monday data point. Please describe in more detail (a) what you observer and (b) what you would like to have changed.

Let me explain what's needed here. I have data from a financial instrument - two columns - first contains the datetime information (stored as a double, bizarrely) and the second is the prices. now I create a FINTS object over them and do a plot on it. The problem is that I end up with something that has blank spaces between the missing dates. I'd like those spaces gone.
