matlab drawing

This article describes how to use matlab to draw.This article includes: line chart x-axis and y-axis, title, legend Column chart fill pattern

Line Chart

How does matlab set the distance between the legend and the x-axis of the graph in the next section

The legend of the line chart needs to know the Legend, which can be set using him

 legend(...,'Location',LOC) adds alegend in the specifiedlocation, LOC, with respect to the axes. LOC may be either a1x4 position vector or one of the following strings:'North' inside plot box near top'South' inside bottom'East' inside right'West' inside left'NorthEast' inside top right (default for 2-D plots)'NorthWest' inside top left'SouthEast' inside bottom right'SouthWest' inside bottom left'NorthOutside' outside plot box near top'SouthOutside' outside bottom'EastOutside' outside right'WestOutside' outside left'NorthEastOutside' outside top right (default for 3-D plots)'NorthWestOutside' outside top left'SouthEastOutside' outside bottom right'SouthWestOutside' outside bottom left'Best' least conflict with data in plot'BestOutside' least unused space outside plot

How to set the x-axis size?

It can be set by set(gca,'xtick',1:1:100);code setting starts from 1 and ends at 100, explain

set(gca,'xtick',start:between two dots:end);

Histogram

How to draw a bar chart and how to fill the bar chart with different patterns?

Matlab histogram fill pattern can be drawn using applyhatch, the following will tell you how to do it

The first step is to copy the file applyhatch.m to your computer.About where to download applyhatch.m, please Baidu, if you can't find it, you can contact me at [email protected]

Don't tell in herenext

The second step is to copy the file to the workbench. What is the workbench is the folder path opened by the software. The path is as shown below

You can modify it yourself, just put the above files in this folder.

The usage is applyhatch(gcf,'\.x.');

The second parameter is to use a different pattern, you can add '/', '\', '|', '-', '+', 'x', '.'several characters

Example:

 close allclear allclc% The computer journal paper% Jigang Wu etc.% copyright: [email protected]% data = [31,32,35;72,73,75;113,114,117;144,146,147;171,173,174;213,215,220];data =[16,17,18;33,34,37;51,54,55;71,74,74;86,91,91;105,113,113];bar(data,1);axis([0 7 0.0 150]);legend('DPA','TSRP','GRP',0);grid on;set(gca,'XTickLabel',{'100','200','300','400','500','600'});xlabel('The number of internal nodes');ylabel('The number of replica that created');set(gcf,'Color','w'); % Set the background color to white, otherwise the color of the area where the coordinate axis appears is grayapplyhatch(gcf,'\.x.');

Copy

For different combinations of histograms, use data=[data 1.1, data 1.2, data 1.3; data 2.1, data 2.2...]

Then draw it, use bar(data,1); The second parameter is the width, try to modify the second value and run it.

The legend can be used. The legend of matlab uses legend('DPA','TSRP','GRP',0); to add the corresponding legend as much as there is data.

Try the following code:

 y=[559006 ,2269384,783762;508559 ,2140905,696001;506491,2007763,735464]bar(y,0.6)legend('n','N','l')grid on;set(gca,'XTickLabel',{'first','second','third'})xlabel('Number of matches')ylabel('Number of results')set (gcf,'Position',[500,500,500,500],'color','w')applyhatch(gcf,'\.x./');set(gcf,'Color','w'); 

Copy
