What interactive graphs are available on Knovel?

Allows you to derive x,y coordinates from a curve that can be expressed as an equation or a row of data in an Interactive Table.

With the Equation Potter you can:

Digitize the curve

1. Define the X and Y units.

   • Example: If Variable (X) represents temperature, define the X-Unit: °R, °F, °C or K. If Function (Y) represents density of liquid, define the Y-unit: g/mL, mg/L, lb/in3, etc.
2. Choose the number of significant digits for X and Y values.
3. While moving the mouse along the curve, click to save X,Y values in the table on the left.

Calculate Y (or X) values from specific X (or Y) values

Click ‘Add Point’, enter the X (or Y) value in the table and press the Enter key.

Delete a point

• From the graph, click the point to delete it, or
• From the table, click the point and delete (keyboard Delete), or
• To delete all points, click ‘Clear All’.

Move a point

On the graph, drag and drop to move a point.

Export or Print results

Click ‘Actions’ in the upper right corner of the screen to:

• Export: Click ‘Export’

  • You can export the tabular data to Microsoft Excel, HTML or Text format, or
  • You can export the graph to JPEG, GIF or PNG format
• Print: Click ‘Print’

  • You can print ‘All’, or
  • You can print the tabular data, or
  • You can print the graph

Allows you to digitize x,y coordinates from normally static graphs.

With the Graph Digitizer you can:

Digitize the curve

1. If necessary, define the X and Y axes representation.
2. Choose the number of significant digits for X and Y values.
3. While moving the mouse along the curve, click to save X,Y values in the table on the left.

Delete a point

• From the graph, click the point to delete it, or
• From the table, click the point and delete (keyboard Delete), or
• To delete all points, click ‘Clear All’

Move a point

On the graph, drag and drop to move a point

Define a ‘Curve Label’ (optional)

If desired, enter a curve label, and click ‘Add’ to place it on the graph. You can drag and drop the label to the desired location within the graph. Please Note: This label will also be displayed in any output such as a print or exported file.

Export or Print results

Click ‘Actions’ in the upper right corner of the screen to:

• Export: Click ‘Export’

  • You can export the tabular data to Microsoft Excel, HTML or Text format, or
  • You can export the graph to JPEG, GIF or PNG format
• Print: Click ‘Print’

  • You can print ‘All’, or
  • You can print the tabular data, or
  • You can print the graph

Allows you to define precise x,y coordinates from individual or multiple curves for data comparison.

With the Graph Plotter you can:

Digitize the curve

1. Define the X and Y units.

   • Example: If the X Axis represents time, define the X-Unit: yr, wk, hr, etc. If the Y Axis represents creep strain, define the Y-unit: vol%, wt%, ppb, %, etc.
2. Choose the number of significant digits for X and Y values.
3. If one of the axis is defined as log, click a data point to save X,Y values in the table on the left, or
4. If both axes are defined as linear, click ‘Scatter points’ to turn off the data points and turn on the curve display, and

   • While moving the mouse along the curve, click as desired to save X,Y values in the table on the left.

Calculate Y (or X) values from specific X (or Y) values

Click ‘Add Point’, enter the X (or Y) value in the table and press the Enter key.

Delete a point

• From the graph, click the point to delete it, or
• From the table, click the point and delete (keyboard Delete), or
• To delete all points, click ‘Clear All’.

Move a point

On the graph, drag and drop to move a point

Curve Label

If desired, enter a curve label. This will replace the current numeric label display on the graph.

Export or Print results

Click ‘Actions’ in the upper right corner of the screen to:

• Export: Click ‘Export’

  • You can export the tabular data to Microsoft Excel, HTML or Text format, or
  • You can export the graph to JPEG, GIF or PNG format
• Print: Click ‘Print’

  • You can print ‘All’, or
  • You can print the tabular data, or
  • You can print the graph

Has the same functionality as a graph digitizer as well as the capability to plot points on a calibrated phase equilibrium diagram. Use the “Lever Rule” to calculate temperatures and compositions of mixture phases (solid, liquid, gas, etc) as temperature and/or pressure change.

With the Phase Diagram Viewer you can:

Use as a graph digitizer

1. If necessary, define the X and Y axes representation.
2. Choose the number of significant digits for X and Y values.
3. While moving the mouse along the curve, click to save X,Y values in the table on the left.

Use the Lever Rule

1. Click the ‘Lever Rule’ button below the table
2. Hover the mouse on the graph area to display a red horizontal line on the diagram.
3. Drag the red line to your desired temperature of interest and click.
4. Click C left and C right points on the red line to define the phase boundaries
5. Click Co point on the line between the phase boundaries to calculate fractional composition of the left and right boundaries

The table on the left is populated with the temperature, C left and C right boundary values, Co value, and f left and f right fractional phases for Co.

Delete a point

Note: In the case of a point that is part of a lever rule, deleting the point will delete all values related to the lever rule.

1. From the graph, click the point to delete it, or
2. From the table, click the point and delete (keyboard Delete), or
3. To delete all points, click ‘Clear All’.

Move a point

You can only move points that were added as graph digitizer points:

• On the graph, drag and drop to move a point

With the Parameterized Graph you can:

Digitize the curve

1. Choose the number of significant digits
2. Click your mouse along a curve in the graph, saving values to the table on the left, or
3. Click in the unshaded area of the graph to automatically plot a point and save its value to the table, or
4. Define the input units (Example: Speed of sound (ft/sec) vs Pressure (psia)), enter input values (such as temperature and speed of sound) and click Plot to plot a point and save its values to the table
