More specifically, I have 15 daily prices so what I did was building a vector from 0 to 15 and use flipr to reverse the order of my raw vector but it doesn't work because also the price of the option was reversed. Theme. Copy. Exp = [0:15]; %days to expiration. P = rand (1,15); %fake daily prices. plot (Exp,P) %is all reversed not just the days ...You can rotate a point by performing a very simple matrix multiplication. Given a point as a 3 element column vector X, the output point X' is simply: X' = R*X. R is a rotation matrix. There are three rotation matrices depending on which axis you want to rotate with respect with.ax contains two handles, one to each axis produced by plotyy. We can use these to set the format of the x-axis using datetick. The two axes have to be set to the same values otherwise you'll get weird overlapping text, and it seems datetick will only handle one axis at a time, hence a loop: for n = 1:2 datetick(ax(n),'x','dd-mmm'); endLearn more about step function plot, reverse y axis .

Create axes with a y -axis on both the left and right sides. Plot a set of data against the left y -axis. Then, use yyaxis right to activate the right side so that subsequent graphics functions target it. Plot a second set of data against the right y -axis and set the limits for the right y -axis. x = linspace(0,10);

Hello, I want to plot a graph with one x axis and two y axes. I want one of the y axes to be reversed i.e. beginning at the top so the data hangs off the top of the graph. Additionally I want the reversed y axis plot to be a bar graph and the other to be an ordinary line plot.More specifically, I have 15 daily prices so what I did was building a vector from 0 to 15 and use flipr to reverse the order of my raw vector but it doesn't work because also the price of the option was reversed.

I have tried several things but no luck. The only way I found is to do it manually. Is there another way?Show activity on this post. The reason why ylim doesn't work if you put it before the plot command is that there is no axes object it can relate to. So there are two options: First, you create an axes object and hold it with hold on, so the upcoming plot is plotted on the same axis. ax = axes; hold on; ylim([0, 1.2])How to reverse the direction of Y-Axis of MatLab figure generated by `imagesc()` function. 12.

ax contains two handles, one to each axis produced by plotyy. We can use these to set the format of the x-axis using datetick. The two axes have to be set to the same values otherwise you'll get weird overlapping text, and it seems datetick will only handle one axis at a time, hence a loop: for n = 1:2 datetick(ax(n),'x','dd-mmm'); end

Hello everyone, i am trying to code stream function in Matlab. i am done with alghoritmic part but having a problem with my contour plot. If you check the result for "u_new" matrix, it starts from 100 at the bottom and go to 0 when we move to upper parts.

Many thanks for your reply. I have already tried set(gca,'Ydir','reverse') before posting this question here. But unfortunately, I am not able to get my desired result. Moreover, when I am using X=-x to flip the x axis, the axis values become negative and I am unable to change them to positive x-axis values.Without being able to run your code this is just speculation, but it looks like you may be double-flipping your Y-axis tick labels. Two lines of code stick out: Theme.

You can change the direction of increasing values by setting the associated property to reverse. For example, setting XDir to reverse, set (gca,'XDir','reverse') produces a plot …Plot Data Against Left y -Axis. Create axes with a y -axis on the left and right sides. The yyaxis left command creates the axes and activates the left side. Subsequent graphics functions, such as plot, target the active side. Plot data against the left y -axis. x = linspace(0,25); y = sin(x/2); yyaxis left. plot(x,y);v = axis returns a row vector containing scaling factors for the x -, y -, and z -axis. v has four or six components depending on whether the current axes is 2-D or 3-D, respectively. The returned values are the current axes' XLim, Ylim, and ZLim properties. axis auto sets MATLAB to its default behavior of computing the current axes' limits ...Commented: Silver on 14 Nov 2018.
