What is Scatter Chart with Dual Y-axis?
- Scatter Charts with Dual Y- axis is a type of chart which is done by using X and Y axis coordinates to display the values for X and dual Y variables
- Scatter Charts with Dual Y- Axis are similar to line graphs which are done with X and dual Y axis where they use X and dual Y axes to plot axis points
- Scatter Charts with Dual Y- Axis show us as per how much X axis is affected by dual Y - axis and the relationship between X-axis and dual Y-Axis is called correlation.
- Scatter Charts with Dual Y- Axis are used when the continuous variable of one Y axis is controlling the experiment and the other continuous variable of Y axis depends on the controlling the experiment
- Scatter Charts with Dual Y - Axis can suggest various kinds of correlations between X - axis and dual Y - axis with a certain confidence interval.
