| 60 | <p> |
|---|
| 61 | Select the <b>crossed arrows</b> button on the plot panel <b>toolbar </b> to drag the plot. |
|---|
| 62 | To disable dragging mode, unselect the same button on the toolbar. |
|---|

| 85 | If the loaded data is a 1-D data.Changing scale or Data Representation will work as |
|---|
| 86 | followed:<b>right click</b> on the plot window. |
|---|
| 87 | A context menu pops-up and select <b>Change Scale</b>. A dialog window titled<b> |
|---|
| 88 | select the scale of the graph</b> will pop-up then change the <b>x</b>, the <b>y</b> |
|---|
| 89 | and the <b>view </b> values as wish. |
|---|
| 90 | The 'view' option includes the axis scale short-cuts such as Linear, Guinier, Cross-sectional (XC) |
|---|
| 91 | Guinier, and Porod plot scale. For a proper data set, these axis scales can be used to estimate |
|---|
| 92 | Rg, Rod diameter, or Backgroud of neutron scattering data respectively (via 'Linear Fit'; see below). |
|---|
| 93 | <br> |
|---|
| 94 | For a 2D image, <b>Right click</b> on the image to pop-up the context |
|---|
| 95 | menu. Select <Toggle linear/Log scale> to switch from linear to log scale. The scale |

|---|
| 101 | <p> |
|---|
| 102 | Linear fit is to perform a line model fitting keeping the scale of the plot. |
|---|
| 103 | Highlight data to fit. |
|---|
| 104 | From the context menu |
|---|
| 105 | select <b> Linear Fit</b>.A dialog window appears. |
|---|
| 106 | Change model initial parameters, data limits |
|---|
| 107 | and hit <b> fit</b> button. |
|---|
| 108 | New parameters values are displayed and the line with the new |
|---|
| 109 | parameters is added to the plot. |
|---|
| 110 | Especially for Guinier, XC Guinier, and Porod plot scale, this 'Linear Fit' will provides Rg, |
|---|
| 111 | Rod diameter, and background, respectively. The following figure shows an example for the Guinier scale. |
