Linear Graphs
- Linear
- Slope
- Intercept
Linear
Linear means straight. A linear graph is a straight line.
In general, a linear graph display function values.
Example
var xValues = [];
var yValues = [];
// Generate values
for (var x = 0; x <= 10; x += 1) {
xValues.push(x);
yValues.push(x);
}
// Display using Plotly
var data = [{
x: xValues,
y: yValues,
mode: "lines"
}];
// Define Layout
var layout = {title: "y = x"};
// Display using Plotly
Plotly.newPlot("myPlot", data, layout);

Slope
The slope is the angle of the graph.
The slope is the a value in a linear graph:
y = ax
In this example, slope = 1.2:
Example
var slope = 1.2;
var xValues = [];
var yValues = [];
// Generate values
for (var x = 0; x <= 10; x += 1) {
xValues.push(x);
yValues.push(x * slope);
}
// Define Data
var data = [{
x: xValues,
y: yValues,
mode: "lines"
}];
// Define Layout
var layout = {title: "Slope=" + slope};
// Display using Plotly
Plotly.newPlot("myPlot", data, layout);

Intercept
The Intercept is the start value of the graph.
The intercept is the b value in a linear graph:
y = ax + b
In this example, slope = 1.2 and intercept = 2:
Example
var slope = 1.2;
var intercept = 7;
var xValues = [];
var yValues = [];
// Generate values
for (var x = 0; x <= 10; x += 1) {
xValues.push(x);
yValues.push(x * slope + intercept);
}
// Define Data
var data = [{
x: xValues,
y: yValues,
mode: "lines"
}];
// Define Layout
var layout = {title: "Slope=" + slope + " Intercept=" + intercept};
// Display using Plotly
Plotly.newPlot("myPlot", data, layout);
