Generating Graphs
After the data has been entered into the worksheet, Graphs can be conducted using this data. There are two ways of creating a graph:
- Using the Graph Wizard.
- Clicking an icon on the toolbar.
In the following examples we are going to use the Graph Wizard to generate bar charts, error bars, 2D line plot and 3D scatter plot.
Bar Charts
1.Shown below is the Clas.xls data imported into SigmaPlot.
2.To open the Graph Wizard, select Create Graph from Graph menu or press F3 key. The Graph Wizard prompts you to specify a graph type. Choose Vertical Bar Chart from the scroll down list. Then click Next.
3.The Graph Wizard prompts you to specify a graph style. Choose Simple Bar from the scroll down list. Then click Next.
4.The Graph Wizard prompts you to select a data format. Choose XY Pair from the scroll down list. Then click Next.
5.The Graph Wizard prompts you to specify the columns of the data you want to graph. Click the column ID in the worksheet to assign it to the X and Mathscor to Bar. Then click Finish.
6.The bar chart generated looks like the one shown below:
Error Bars
1.To open the Graph Wizard, select Create Graph from Graph menu or press F3 key. The Graph Wizard prompts you to specify a graph type. Choose Scatter Plot from the list of Graph Types and click Next.
2.The Graph Wizard prompts you to specify a graph style. Choose Simple Error Bars from the list of Graph Styles and click Next.
3.The Graph Wizard prompts you to specify Symbol value and Error calculation (upper, lower). Choose Column Means from the scroll down list as the symbol value. Choose Standard Deviation for both of upper and lower Error calculation. Then click Next.
4.The Graph Wizard prompts you to select a data format. Choose Many Y and then click Next.
5.The Graph Wizard prompts you to specify the columns of the data you want to graph. Click the column Mathscor in the worksheet to assign it to Y1, Compscor to Y2, canx to Y3, C5 to Y4 and M5 to Y5. Then click Finish.
6.The error bar generated looks like the one shown below:
2D Line Plot
1.To open the Graph Wizard, select Create Graph from Graph menu or press F3 key. Select Line Plot, and then click Next.
2.Select Simple Straight Line, and then click Next.
3.Select XY Pair, and then click Next.
4.Select ID on the worksheet for X, and canx for Y, then click Finish.
5.A generated 2D line plot looks like the one shown below:
3D Scatter Plot
1.To open the Graph Wizard, select Create Graph from Graph menu or press F3 key. The Graph Wizard prompts you to specify a graph type. Choose 3D Scatter Plot from the list of Graph Types and click Next.
2.The Graph Wizard prompts you to select a data format. Choose XYZ Triplet and then click Next.
3.The Graph Wizard prompts you to specify the columns of the data you want to graph. Click the column Mathscor in the worksheet to assign it to X, Compscor to Y and canx to Z. Then click Finish.
4.A generated 3D scatter plot looks like the one shown below:
