- The following charts are delivered as samples in the directory
- C:\Program Files\VRCharts\Samples. It is distributed as a self-
- extracting executable file. Simply execute the Samples.exe file
- and it will expand into the samples described in the documentation.
- After expanding, start VRCharts and select the File menu item,
- select Preferences and click the Directory/Folder tab. Set all the
- folders to C:\Program Files\VRCharts\Samples and continue with
- the tutorial documentation in Chapter 3 of the manual.
-
- Input data files all have the file extension .txt
- and are tab delimited files. Most charts use the data
- file Sample1.txt while a few, that require split data, use
- SampleSplit.txt. Specific data is required to make
- certain charts such as the Ribbon Highway Chart and the input
- file is identified in the listing below. For each chart, the name
- of the input data if it is not the default, is listed along
- with the chart definition file (.vrd) and the display file (.wrl).
-
- Following is a description of each chart:
-
- 1. Sample1 - This is the same as the Area chart
- Input Data File: Sample1.txt
- Chart Definition File: Sample1.vrd
- Display Chart File: Sample1.wrl
-
-
- 2. AREA CHART
- Sample1-Area.vrd
- Sample1-Area.wrl+
-
- Probably one of the most effective presentation charts is the
- Area chart. Adding the transparency attribute to this chart
- makes a dramatic visual improvement. We are then able to see
- through areas. And, if this was not enough, you can select one
- of the areas of the chart and "pull it out" such that the
- entire area moves outside the edges of the X, Y and Z coordinates
- (see enhanced features, selected objects). Truly awesome!!
-
-
- 3. BAR AND COLUMN CHART
- Sample1-Bar.vrd
- Sample1-Bar.wrl
-
- Bar and column charts have been the mainstay of presentation
- graphics for years. They are easy to produce, provide great
- visual feedback and are excellent at conveying the comparison
- of associated numeric data. As with all VRCharts produced charts,
- we are able to enhance this presentation tool by mapping of
- transparency and glow to the bars or columns. And, with the
- virtual reality ability to move around in your environment,
- you can now chart huge amounts of information on one chart and
- easily isolate and display only the portion of interest during
- that particular presentation.
-
-
- 4. PIE CHART
- Sample1-Pie.vrd
- Sample1-Pie.wrl
-
- With VRCharts even standard old PIE charts take on a new life.
- We can now map the attributes of transparency and glow to any
- wedge of the pie.
-
-
- 5. PIE CHART with wedge size one set of data and wedge
- height another set of data
- SampleSplit.txt
- Sample1-Pie02.vrd
- Sample1-Pie02.wrl
-
- With split data processing, the height of each wedge can
- now be attached to a different column than the size of the wedge.
- This allows us to assign more data variable to a single pie chart
- and with the added dimension provided by VRCharts, we are able to
- fly around the pie and view from various angles. The standard
- single pie chart can also be combined with other pies to form
- a Tank Farm Chart.
-
-
- 6. SCATTER CHART with ribbon connecting points. The top
- ribbon of an area chart.
- Sample1-RibbonScatter.vrd
- Sample1-RibbonScatter.wrl
-
- Once freed of two dimensions, scatter plots can represent
- multiple variables along additional parallel axes in the third
- dimension; the use of color and symbols can add even more
- dimensions to the data as it is plotted.
-
-
- 7. 3-D LINES CHART - same as 6 with lines connecting the points.
- Sample1-ScatterLine.vrd
- Sample1-ScatterLine.wrl
-
- This is similar to the Area Chart but it shows just the top of
- the area. With the virtual reality view you are able to put many
- 3-D Lines on the same chart and since you can fly through and
- move around in the view you can isolate and just see the ones
- you are really interested in examining in greater detail.
-
- 8. SIMPLE SURFACE CHART
- Sample1-Surface.vrd
- Sample1-Surface.wrl
-
- Surface charts are good for representing large amounts of data.
- Our Ribbon Highway Chart is a bounded surface chart. Simply set
- the Chart Width longer than the height and depth to obtain a
- Ribbon Highway chart.
-
-
- 9. DUAL SURFACE CHART - requires split data file.
- SampleSplit.txt
- Sample-DualSurface.vrd
- Sample-DualSurface.wrl
-
- When two surfaces are used to represent two sets of data we have
- a dual surface chart. The surfaces can intersect when data
- points overlap, or will be floating one above the other,
- depending on the data. This example of a Dual Surface Chart
- shows data that intersects.
-
-
- 10. FOG CITY CHART with simple data file. The fog is the same
- level as the top of the bars.
- Sample-FogCity.vrd
- Sample-FogCity.wrl
-
- In this version of Fog City the fog simply hangs on the top of
- the buildings (columns). The more interesting example is the
- following one.
-
-
- 11. FOG CITY CHART - with Split data file. Fog is one set of
- data and the column (or buildings) are another set of data.
- SampleSplit.txt
- Sample-FogCitySplit.vrd
- Sample-FogCitySplit.wrl
-
- Fog City with split data is a terrific chart to compare actual
- results to expected results. The fog becomes the expected and
- the bars become the actual. It is obvious where you are above
- or below your projected goals. This same concept could then be
- applied in a number of areas. For example: the expected could
- be a national average for spending by category for other
- businesses in your same industry. The bar
- then becomes your spending in these areas and you can immediately see
- how you are doing relative to the national average. While this
- example only shows a few categories and periods, there could be
- many more without losing meaning. In fact, comparing multiple
- years by quarter might produce an interesting trend.
-
-
- 12. LOBSTER BUOY CHART - with split data file. Surface is one set
- while buoys are another.
- SampleSplit.txt
- Sample-LobsterBuoy.wrl
- Sample-LosterBuoy.vrd
-
- When you grow up off the coast of Maine, you see the tops of many
- lobster buoys. You know they are connected to the bottom with a
- line anchoring them in place. We have created the equivalent of
- this concept by creating a chart where the data points are various
- shaped "buoys" and they are anchored to the XY grid plane.
- You are able to specify the transparency of the "ocean" surface
- so it can go from completely opaque to transparent, depending on
- your needs. The surface can represent one set of data and the data points
- another. This provides a variance from the expected depending
- on whether the buoy points are above the surface or below.
-
-
- 13. Ribbon Highway Chart showing 15 years of T-Bill rates for
- various time frames.
- Sample-RibbonHighwayTBill.txt
- Sample-RibbonHighwayTBill.vrd
- Sample-RibbonHighwayTBill.wrl
-
- This is an example of a Ribbon Highway Chart that is a spreadsheet
- that is 11 columns of data and 780 rows deep. It represents
- interest rates for 15 years of various T-Bills.
-
-
- 14. TANK FARM CHART
-
- Sample-TankFarm.vrd
- Sample-TankFarm.wrl
-
- Tank Farm is the most complex chart type produced by VRCharts.
- It is a group of pie charts. As with all VRCharts, the color
- and transparency of each piece of each pie can be dependent on
- a different set of data. Also, the height of each piece of pie
- can be dependent on data.
-
- Generally this is good when you have many columns of data but
- only a few rows in your spreadsheet. Each pie represents one row.
- Now you can assign data columns to attributes (size, height, color,
- transparency, glow) of the various pieces of the pie.
- When done correctly this one chart can often be the major screen in
- any presentation. Because there is so much information in one chart,
- it is frequently best, during a presentation, to have several
- simpler versions leading up to the final complete one.
