3d Plot In Matlab From Excel Data

Plotting surface of a subset of 2d matrix in matlab.

3d plot in matlab from excel data. Im new to matlab and have a matrix with a set of x values and 24 different sets of y values. Create an interpolant z f xy. Show hide all comments. This is the point in which you will relate xx yy and zz together.

From the z components in the matrix zz the surf command will create a 3 d shaded surface. As we can see the working of a surface chart is in the colors. How can i plot a 3d surface from excel data. What would be the correct code to import the data and plot theses variables.

Xyz mesh is a program used to generate 3d data and images from xyz or mesh inputs. I normally represent them as 24 2d plots overlayed but id like to plot a 3d graph with this data. Enter the command p plot indep dep1 indep dep2 in the command window. Select the data in which we want to plot the 3d chart.

Ask question asked 1 year 11 months ago. How do i include the y values and plot a 3d scatter or surface plot. Evaluate the interpolant at the grid points mesh xyz. What this means is once the data is convert its possible to export the data directly into a new excel document or copy and paste it into a preexisting one.

I need to plot 3d and also import the data from excel. Now in the insert tab under the charts section click on the surface chart. Surf plot after rotating my data. Using the data from the example above.

I have freq angle and power as 3 variables and plot them as freq vs angle vs power. Plot the interpolated mesh. Active 1 year 11 months ago. Matlab surf meshgrid issue 2 vectors 1 matrix surface plot.

Create a regular grid f triscatteredinterp xyz. Xy meshgrid linspace 0120. Discover what matlab. Matlab is a very powerful tool for scientific analysis and used in engineering for solving the complex problems mathematically and numerically.

It is the only program available that exports all converted data into excels native formats. A normal 3d surface plot in excel appears below but we cannot read much from this chart as of now. If you wish to graph more than two dependent variables follow the same format and add a dep3 variable.
