3. Basic Editing Operations

3.1 The Left Side of Your Screen

Notice that there are four icons on the left side of your screen. The top one allows you to return to the top level, from which we started. The second one allows you to add filters to remove any unwanted information from your visualization. In other words, you can further restrict the result of a query that placed information on the screen. In this guide, we will assume that a data base administrato (DBA) has selected the queries which you can use to populate your screens. To see all the queries available, return to the top screen and click on the data icon. If you want to add other queries, consult with your DBA or “have at it” if you are conversant in SQL. Also, from the top level you can see the icon libraries available to you. This is where the “beaker” icon came from, which you have already seen. In this section we will focus on the fourth button, the Hopara visualization studio. Through this button you can change many aspects of a visualization. The remaining “movement” button allows you to move incorrectly placed data, through manual editing.

Before we start, here are a few things that you should have noted from Section 2:

You can click on the “+” and “-“ buttons to “jump zoom/unzoom”. Rather arbitrarily Hopara has 23 “levels” that you can move to. These are labeled 0 through 22 as we will see momentarily.

You can also use the scroll feature to continuously zoom in or out. In effect, the geographic map gets larger or smaller incrementally. Hence, the 23 zoom levels are simply levels in what is really a continuum.

Some things are fixed size, such as the beakers in the “basic labs” application.

You can also note that at particular zoom levels, the beaker and the floorplan map appear and disappear.

This section shows how to construct these effects and others. Now click on the visual studio button, and you will see the display of Figure 9.

An important concept in Hopara is “layers”. “Layers” determine what you see at any level of zoom. You will note that there are 3 layers in the Basic Labs visualization which are presented on a background map of the world. “Labs Overview” shows the beakers, while “floorplan” indicates the walls of each laboratory. Lastly, “assets” shows an icon for each sensor indicating pictorially where the sensor is located as well as sensor-specific information.

Click on “Labs Overview” to see the screen of Figure 10. Note that labs overview is of type icon (in this case the beaker) and there are 6 tabs with more detailed information. Click on the “appearance” tab and you can see that the beaker icon comes out of the science library. Note that you can change the size of the beaker you wish. Also, note that the color of the icon is determined by the “alert level” field and that the color scheme is red/yellow/blue. You can change it to the more common red/yellow/green if you wish. The “details” tab shows what the tool tip will indicate when hovering.

Now click on the important “visibility” button. You can see that the beaker” icon is visible from level 0 all the way to level 13. You can move the levels that the beaker is visible by changing the sliders. You can also see that hovering over the lab displays the four pieces of data indicated. Now click on the “position” tab, which indicates that the (latitude, longitude) position comes out of the database, as part of the “labs_overview” query. This query is shown under the “data” tab.

Now return to Figure 1, and position yourself on the red lab. Zoom in until you see the display of Figure 11. Notice there is a floorplan for the red lab with assets shown.

Notice also that a button on the right hand side is present to indicate that there are two floor in the lab and we are on the first floor. You can move to the second floor if you wish. Back on the first floor notice there are icons displayed in red (critical) and ones in yellow (warning). Click on the center yellow icon to see the display of Figure 12. Here we note that there is a icon for a 3-D model of the Keysight refrigerator. When clicked, we get the display shown in Figure 13. Clicking on temperature history gives you Figure 14.

Notice that we began with a geographic map with icons on it, zoomed to a floorplan, and then jumped to a temperature history. This shows the flexibility and power of Hopara and is obviously not possible in Google Maps.

There are additional features in the visualization studio that we will cover in an advanced user guide. In the final section of this basic guide, we will deal with moving objects around on the display.
