Arithmetic Operations (Beta)

The basic arithmetic operations that you can perform on sensor data while plotting the graph is -

• Addition (Can also be used for subtraction)
• Multiplication (Can also be used for division)

Addition

You can add any value to the sensor data by the using the function add() and this function must be called before the plotChart function. The function takes an integer value as input. You can use the function to also subtract values by passing a negative integer as input to the function. The function internally performs the operation on the hardware input value that has been defined in your plotChart function.

Sample Code

setChartLibrary('google-chart');
setChartTitle('Your Graph Title');
setChartType('lineGraph');
setAxisName('X-Axis Name','Y-axis Name');
add(Integer Value);
plotChart('time_stamp','your_variable_name');

*Note: This function will not work in the stepped and multiple graph.

Multiplication

You can multiply any integer value to sensor data by the using the function mul() and this function must be called before the plotChart function. The function takes an integer value as input. You can use the function to also divide values by passing a decimal value as input to the function. e.g. to divide your sensor value by 20, pass the decimal value of (1/20) i.e. 0.05 as input to the function. The function internally performs the operation on the hardware input value that has been defined in your plotChart function.

Sample Code

setChartLibrary('google-chart');
setChartTitle('Your Graph Title');
setChartType('lineGraph');
setAxisName('X-Axis Name','Y-axis Name');
mul(Integer Value);
plotChart('time_stamp','your_variable_name');

Note: This function will not work in the stepped and multiple graph
