Contour Plots
A plot that represents a 3D surface by plotting on a 2D grid.
Try an Example
Before getting started with your own dataset, you can check out an example. First, select the 'Type' menu. Hovering the mouse over the chart type icon will display three options: 1) Charts like this by Chart Studio users 2) View tutorials on this chart type 3) See a basic example.
Clicking the 'See a basic example' option will show what a sample chart looks like after adding data and editing with the style. You'll also see what labels and style attributes were selected for this specific chart, as well as the end result.
You can also use the data featured in this tutorial by clicking on 'Open This Data in Chart Studio' on the left-hand side. It'll open in your workspace.
Add Data
Head to Chart Studio and add your data. You have the option of typing directly in the grid, uploading your file, or entering the URL of an online dataset. Chart Studio accepts .xls, .xlsx, or .csv files. For more information on how to enter your data, see this tutorial.
Create Chart
After adding data, go to the 'Traces' section under the 'Structure' menu on the left-hand side. Choose the 'Type' of trace, then choose 'Contour' under 'Simple' chart type.
Next, fill out the necessary 'X', 'Y' and 'Z' values from their respective dropdown menus. This will create a contour, as seen below. In this example, our data was formatted as a Z matrix so we will add all columns of our dataset to the 'Z' dropdown. We do not have to specify 'X' or 'Y' data in this example, so we will leave those dropdown fields empty.
Style Chart
The 'Style' menu displays many options to modify characteristics of the overall chart layout or the individual traces. To see more options about styling the chart, visit the style and layout section of the Chart Studio documentation.
Use the 'General' section under the 'Style' menu to set the plot title, as well as change the layout background, margin color and font styles.
To set the plot title, type the title text within the textbox provided under 'Title.'
Another approach is to click and then enter the title directly on the plot interface. The same can be done for the axes title and the legends.
Use the 'Traces' section under the 'Style' menu to change the properties of the traces, such as color gradients, contours, or line attributes.
Save and Share
To save the plot, click the 'Save' button on the left-hand side. A save modal will appear, as seen below, where you can specify the filenames and privacy settings for your plot and data grid.
