Multiple Google gauges?
I have a google gauge that shows my PM2.5 sensor values but I would like to make 3 gauges appear side by side that show the value of different sensors. How can I do that? Thanks

You can create a custom MATLAB visualization with your gauges.
I've made a gage with ploarplot where theta is the value you want to show. Here is some code to get you started.
f=tiledlayout(1,3); nexttile(f); rho = linspace(1,10,5); theta = 3/4*pi*ones(1,5); myLineWidth = 4; polarplot(theta,rho,'LineWidth',myLineWidth) nexttile(f); polarplot(theta*1.5,rho,'k','LineWidth',myLineWidth); nexttile(f); polarplot(theta*2.5,rho,'r','LineWidth',myLineWidth);
Thank you, but do you know how to implement it on google gauge?
Or is there any way to make 3 widgets appear in one window, side by side? The reason why I dont use polarplot is because I want to show my sensor values which are not in degree
You can scale the sensor values by the degrees in a circle. If you gauge has a total range of 100, and value= measurement then the position of the line in degrees is
position = 360/100* measurement
or in radians
position = 2* pi()/100 * measurement
In fact, you can make a function that creates the plots that takes in the current measurement and the gauge range as arguments and then generates the output. You can read the present value from you channel using thingSpeakRead.
