## How do you change the color of a loop?

Simply replace: Color myC = new Color(((255/stepSize)*(stepSize-i)), 0, (255/stepSize)*i ); by: final Color myC = new Color(((255 / count) * (count – i)), 0, (255 / count) * i);

## How do you add color to a plot in Matlab?

Answers (1) % plot your lines and they will be plotted with these colors in order. plot(x2,y,2); Then plot your other lines plot(x,y,’Color’,color);

**How do I generate a random color in Matlab?**

Direct link to this answer

- just feed it with three random numbers between 0 and 1 (rand), or random rounded numbers for only 0 and 1.
- ex:
- randcolor = [round(rand) round(rand) round(rand)]
- EDIT: just did a little playing around with the plot function..
- plot(your_plot,’color’,[rand rand rand])

### How do you plot a red line in Matlab?

Specify Combinations of Colors, Line Styles, and Markers Create a plot with a red dashed line and circular markers by specifying the linespec argument as ‘–or’ . For this combination, ‘–‘ corresponds to a dashed line, ‘o’ corresponds to circular markers, and ‘r’ corresponds to red.

### How do I use RGB color in MATLAB?

For example, at these RGB Color websites, you will be given R=255, G=0, B=0 for red. So you can use 1/255[255,0,0] to get the color of red to use as a color in MATLAB.

## How do you make a legend in Matlab?

Set the DisplayName property as a name-value pair when calling the plotting functions. Then, call the legend command to create the legend. Legends automatically update when you add or delete a data series. If you add more data to the axes, use the DisplayName property to specify the labels.

**How will you specify marker & color in a line plot?**

The blue line is plotted using the solid line style, plus sign marker and blue color. The yellow line is plotted using the dashed line style, Asterisk marker, and yellow color. The green line is plotted using the dotted line style, diamond marker, and green color.

### How do I specify colors in Matplotlib?

Matplotlib recognizes the following formats to specify a color:

- an RGB or RGBA (red, green, blue, alpha) tuple of float values in [0, 1] (e.g., (0.1, 0.2, 0.5) or (0.1, 0.2, 0.5, 0.3) );
- a hex RGB or RGBA string (e.g., ‘#0f0f0f’ or ‘#0f0f0f80’ ; case-insensitive);

### How do I get Orange in MATLAB?

- You can change the color by using full names color=”red”.
- You can change the color by using hex strings (‘#008000’).

## How to define visually distinct colors for 10 plots in MATLAB?

For 10 plots, you obviously cannot rely on the default ColorOrder, so a great way to define N visually distinct colors is with the “Generate Maximally Perceptually-Distinct Colors” (GMPDC) submission on the MATLAB Central File File Exchange. It is best described in the author’s own words:

## How to plot 10 line plot with different colors?

If you want subsequent plots use different colors, use hold all instead. That way the standard 7 line colors are used in turn. Since you have 10 lines to plot, you might want to specify the colors explicitly to make sure they are all different.

**How many colors can you cycle through in MATLAB?**

However, by default MATLAB only specifies a short list of colors (just 7 as of R2013b) to cycle through, and on the other hand it can be problematic to find a good set of colors for more data series.

### How do I customize the color of the plotting data?

You can customize the colors if you need to. Many plotting functions have an input argument such as c or colorspec for customizing the color. The objects returned by these functions typically have properties for controlling the color.
