# Gallery of chart types

It is important to remember that while your data can be presented with a number of different charts, the message you want to convey to your audience dictates the chart you ultimately use. The following sections present examples of the types of charts that Calc provides, with some of the tweaks that each sort can have and some notes as to what purpose you might have for that chart type. For details, see the Help.

## 柱形圖

Column charts are commonly used for data that shows trends over time. They are best for charts that have a relatively small number of data points. (For large time series a line chart would be better.) It is the default chart type, as it is one of the most useful charts and the easiest to understand.

## 環圈圖

If you want to show the proportional nature of your data but want to include more than one data series, a donut chart is your best option. The extra layer attempts to give pies another dimension of time. However, two or three data series are all you can include before it becomes meaningless. The extra layer attempts to give pies another dimension of time.

As with pie chart, you can explode the pieces of the donut chart. You can also separate individual pieces as in pie charts.

Donut charts

As in pie charts, data labeling may be used a substitute for the legend, not an addition to it.

## 平面圖

An area chart is a version of a line or column graph. It may be useful where you wish to emphasize volume of change. Area charts have a greater visual impact than a line chart, but the data you use will make a difference.

Area charts—the good, the bad, and the ugly

As shown above, an area chart is sometimes tricky to use. This may be one good reason to use transparency values in an area chart.

• Chart wizard > no y-grids. As the data overlaps, some of it is missing behind the first data series. This is not what you want. A better solution is Chart 2.
• Chart wizard > no y-grids > Object Properties > Area > 50% Transparency; Labels > Tile 55° . The transparency makes it easy to see the data hidden behind the first data series.
• Chart wizard > 3D > realistic > no y-grids > Object Properties > Area > 50% transparency. We also twisted the chart area around and gave the chart wall a picture of the sky. As you can see, the legend turns into labels on the z-axis. But overall, though it is visually more appealing, it is more difficult to see the point you are trying to make with the data.

Other ways of visualizing the same data series are represented by the stacked area chart or the percentage stacked area chart. The first does what it says, each number of each series is added to the others so that it shows an overall volume not a comparison of the data. The percentage stacked chart shows each value in the series as a part of the whole. For example in June all three values are added together and that number represents 100%. The individual values are a percentage of that. Many charts have varieties which have this option.

## 線圖

Things to do with lines: thicken them up, make them 3D, smooth the contours, just use points.

3D lines confuse the viewer, so just using a thicker line often works better.

Line charts

## 散佈 or XY 圖

Scatter charts are great for visualizing data that you have not had time to analyze, and they may be the best for data when you have a constant value with which to compare the data; for example, weather data, reactions under different acidity levels, conditions at altitude, or any data which matches two series of numeric data. In contrast to line charts, the x-axis are the left to right labels which usually indicate a time series.

A particularly volatile time in the world currency market.

There is a catch with scatter charts that may surprise those unfamiliar with how they work. One data series represents the x-axis and the next represents the y-axis. The chart becomes a Cartesian map with each point showing the (x,y) point of each pair of data. Thus you may be hoping for a chart with two series of points, as you would get in a line chart, and only have one unexpectedly twisted line. Each additional series of data is matched against the original series. Figure 30 shows a comparison of three currencies with the Japanese Yen. Even though the table presents the monthly series, the chart does not. In fact the Japanese Yen does not appear; it is merely used as the constant series that all the other data series are compared to.

## Net 圖

A net chart is similar to polar or radar graphs. They are useful for comparing data that are not time series, but show different circumstances, such as variables in a scientific experiment or direction. The poles of the net chart are the y-axes of other charts. Generally, between three and eight axes are best, any more and this type of chart becomes confusing. Before and after can be plotted on the same chart, or perhaps expected and real results, so that differences can be compared.

• Plain net chart without grids and with just points no lines.
• Net chart with lines and points and grid. axes colors changed as well as labels. chart area color = gradient quadrant and the points changed to fancy 3D ones.

There are also varieties of net chart that show the data series as stacked numbers or stacked percentages.

A stock chart is a specialized column graph specifically for stocks and shares. You can choose traditional lines, candlestick, and two-column type charts. The data required for these charts is quite specialized, with series for opening price, closing price, and high and low prices. Of course the x-axis represents a time series.

When you set up a stock chart in the Chart Wizard, the Data Series dialog is very important. You need to tell it which series is for the opening price, closing price, high and low price of the stock, or else the chart may be indecipherable. The sample table for this chapter needed to be changed to fit the data series.

A nice touch is that OpenOffice.org Chart color-codes the rising and falling shares: white for rising and black for falling in the candlestick chart, and red and blue in the traditional line chart.

## 欄與行圖

A column and line chart is a combination of two other chart types. It is useful for combining two distinct but related data series, for example sales over time (column) and the profit margin trends (line).

You can choose the number of columns and lines in the Chart Wizard. So for example you might have two columns with two lines to represent two product lines with the sales figures and profit margins of both.

Column and line chart

The chart has data for two products, manufacturing costs and profits over a period of time, in this case, six months in 2007. We highlighted the table and started the Chart Wizard. We chose the Column and Line chart type with two lines and the data series in rows. Then we gave it a title to highlight the aspect we want to show. The lines are different colors at this stage and don’t reflect the product relationships. When we finished with the Chart Wizard, we highlighted the chart, clicked on the line, right-clicked, and chose Object properties > Line.

On this tab there are a few things to change, first the color to match the products, so both Ark Manufacturing and profit are blue and Prall is red. I think the lines need to be more noticeable so I made the lines thicker by increasing the width to .08.

The background is done by highlighting the chart wall and right-clicking, choosing Object Properties > Area, and changing the drop-down box to show Gradient. We chose one of the preset gradient patterns and made it lighter by going to the Transparency tab and making the gradient 50% transparent.

We also decided that the chart looked cleaner without the grid so we went to Insert > Grids and unchecked the X-axis option.
