1 Viewing Data One of Lavastorm Desktop Professional s many features and benefits is the ability to see data from any part of the analytic process from the beginning, throughout the middle and at the end. Lavastorm Desktop s BRDViewer not only provides the ability to see your data in tabular format; it also allow you to perform some additional analysis. Accessing the BRDViewer Any data processed by Lavastorm Desktop Professional can be viewed in the BRDViewer. To launch the BRDViewer, simply double-click on any node input or output pin as shown in Figure 1. Figure 1. Double-click on the input and output pins to launch the BRDViewer. By default, the BRDViewer displays the first 1000 rows of data (Figure 2). This default value can be modified by changing the Viewer Max Records in the Preferences found under the tool menu. 1 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 1

2 Figure 2. BRDViewer. You can access the BRDViewer menu (Figure 3) by right-clicking on any of the input or output pins. In the menu, View Data displays the first x records where x is the value defined in the graph preferences (1000 by default). View Data (All) will load all the data into the BRDViewer. View Fields shows the data fields names and data types (Figure 4). Figure 3. BRDViewer Right-Click menu 2 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 2

3 Figure 4. View Fields output Viewing Data in the BRDViewer Sorting Data Data can be sorted in the BRDViewer by first selecting an item in the column you want to sort or by selecting the entire column and then clicking on the sort button. Similar items will be grouped together and shaded for easy viewing analysis as shown in Figure 5. 3 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 3

4 Figure 5. Sorting Data in the BRDViewer Changing the Column Order and Size in the BRDViewer The BRDViewer gives the user the ability to easily change the column order. Selecting a column name in the Columns menu will move the selected column to the beginning of the dataset. To save the new column order, select Reorder Columns on Load from the Preferences menu. The new column order will then be carried throughout your analytic graph. To clear the saved column order, select Clear memorized column order from the Actions menu. Reset Column Order in the Action Menu will change the column order back to the original order; however, it will not change the saved column order. 4 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 4

5 To expand all columns to the length of the longest item within the column, double-click on the blank header cell above the row numbers and to the left of the column headings (Figure 6). Figure 6. Expand all Column Widths. Individual columns can be sized by placing the cursor in between the column headings. When the cursor changes to double arrows, the column size can be changed by clicking and dragging the mouse. Creating a Histogram of the Data A histogram displaying the data distribution can be created from the BRDViewer. First click on either the column name or on a data point within the column you are interested in. Press the Histogram button as shown in Figure 7 to create the Histogram (Figure 8). 5 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 5

7 Figure 8. Data Distribution The histogram in Figure 8 shows the data distribution for one column of data. A complex histogram can be created by selecting multiple data columns (Figure 9). Pressing the CTRL key while selecting the columns with the mouse allows for multiple column selection. The complex histogram displays the data distribution for combinations of data (Figure 10). 7 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 7

9 Figure 10. Data Distribution for Multiple Columns Saving and Copying Data in the BRDViewer Saving Data There are multiple ways that data can be saved and copied from within the BRDViewer. Pressing CTRL-S or selecting Save as BRAIN from the File menu will save the data as a BRD file which is Lavastorm Desktop s native data format. A BRD file can be opened separately from the graph by double-clicking on it in Windows Explorer. The data will appear in the BRDViewer. BRD data can also be acquired into any Lavastorm Desktop graph using the BRD file node. Selecting Save as Excel from the File menu allows the user to save the data in an Excel file. Copying Data Data can be copied from the BRDViewer and pasted in a variety of formats. The Copy command from the Edit menu will copy the selected data along with the column headings as text which can be pasted into documents and text files. Copy as Excel copies the selected data and the corresponding column headings and allows the user to paste the data into cells in an excel worksheet. 9 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 9

10 Copy as Examine The Copy as Examine function from the Edit menu allows the user to quickly and easily extract a subset of data and copy it into the BRE graph. To use the Copy as Examine function, select the record(s) to be extracted from the data. Then right-click on the graph canvas and select Paste. A filter node which contains the filter criteria copied from the BRDViewer will be created on the graph canvas. The output of the original data source needs to be connected to the input of the newly created filter node. The Filter node will output the records filtered by the data that was copied after it is run. Color-Coding the Data Data in the BRDViewer can be color-coded for a quick visual analysis of the data. Three colorcoding options are available blue, red and inverted. The cell with the data value to color-code must first be selected. Next, click on the red or blue pen or the paintbrush (inverted color) to bring up the color menu (Figure 11). The color menu specifies how the data should be colorcoded. The gray pen in the color-coding toolbar will clear the data of any color-coding. Figure 11. Color-Coded Data The color-coded results from the BRDViewer can be copied to the BRE graph using the Create Colorized Filter Node function (Figure 12). After the data is colored-coded, press the Create 10 Lavastorm Desktop Professional Tech Note Lavastorm Analytics Page 10

11 Colorized Filter Node button from the toolbar. Right-clicking on the graph and selecting Paste will then create a filter node with multiple outputs as shown in Figure 13. The Filter node s first output pin contains the records that have no color-coding based on the criteria selected in the BRDViewer. Output pins for red, blue, purple (combination red and blue results) and inverted may be present in the filter node depending on the color-coding applied in the BRDViewer. Figure 12.
