**TIP:** This tool is design for correlation visualizetion, which provided several ways to represente correlation of multi-series, for example color, number...

**Discription**

- This tool offer a graphical display of a correlation matrix. There are two ways in each plot to visualize correlation matrix. First one is color, the more correlation close to 1 the more blue the color is, on the other hand, the more correlation close to -1 the more red the color is. Then we also have some graphical feature to visualize correlation, which is in mapping method. We have square, circle, ellipse, shade, pie. In these methods the more correlated the big such figure in each rectangular. We also provide number method, which will give you the each correlation in correlation matrix.
- Note in ellipse and pie there will be a direction on your plot, that is similar to correlation, positive correlation will have a upward pattern and negative correlation will have a downward pattern, which in consistent with regression result using such data.
- In this tool we also provided changing Pannel and Diagonal part of your plot, in this section you are able to draw a more flexible picture. Then you are also able to add correlation coeffcient to the picture if it does not using number method and you want to see the exact correlation number. Finally, we offer different color palette to visual your correlation matrix.

- Here is the option I use to plot the picture above. Data set is scatter.txt.

- Then we consider pie method.
