The horizontal bar graph is minor variation on the bar chart which can be useful when you have larger labels, since you have more space available to you for them.
The example file is here.
<script> window.onload = function () { var data = [280,45,133,166,84,259,266,960,219,311]; var hbar = new RGraph.HBar('myCanvas', data); hbar.Set('chart.labels', ['Richard', 'Alex', 'Nick', 'Scott', 'Kjnell', 'Doug', 'Charles', 'Michelle', 'Mark', 'Alison']); hbar.Set('chart.gutter', 45); hbar.Set('chart.background.barcolor1', 'rgba(255,255,255,1)'); hbar.Set('chart.background.barcolor2', 'rgba(255,255,255,1)'); hbar.Set('chart.background.grid', true); hbar.Set('chart.colors', ['rgba(255,0,0,1)']); hbar.Draw(); } </script>
You can use these properties to control how the bar graph apears. You can set them by using the Set() method. Eg:
myHBar.Set('name', 'value');
chart.gutter | The gutter of the graph. This is the area outside of the X and Y axis - where the labels go. If you're short on space for your labels, try increasing this. Default: 25 |
chart.colors | An array of the colors of the actual bars. Default: An array - ['rgb(0,0,255)', '#0f0', '#00f', '#ff0', '#0ff', '#0f0'] |
---|---|---|---|
chart.background.barcolor1 | The color of the background bars, (1 of 2). Default: white |
chart.background.barcolor2 | The color of the background bars, (2 of 2). Default: white |
chart.background.grid | Whether to show the background grid or not. Default: true |
chart.background.grid.color | The color of the background grid. Default: #ddd |
chart.background.grid.hsize | The horizontal background grid size. Default: 40 |
chart.background.grid.vsize | The vertical background grid size. Default: 18 |
chart.background.grid.width | The width that the background grid lines are. Decimals (eg 0.5) are permitted. Default: 0.5 |
chart.background.grid.border | Determines whether a border line is drawn around the grid. Default: true |
chart.background.grid.hlines | Determines whether to draw the horizontal grid lines. Default: true |
chart.background.grid.vlines | Determines whether to draw the vertical grid lines. Default: true |
chart.labels | An array of the labels to be used on the graph. Default: An empty array |
chart.labels.above | This is a boolean which if true, will cause labels to be shown to the right of the bars. (It's called "above" for API compatibility). Default: false |

chart.text.size | The size (in points) of the labels. Default: 10 |
chart.title | The title of the graph, if any. Default: null |
chart.title.vpos | This allows you to completely override the vertical positioning of the title. It should be a number between 0 and 1, and is multiplied with the gutter and then used as the vertical position. It can be useful if you need to have a large gutter. Default: null |
chart.title.color | The color of the title. Default: black |
chart.xmax | (Optional) An optional max figure for the X scale. Default: none (one is calculated) |
chart.axis.color | The color of the axes. Default: black |
chart.grouping | How the bars are grouped, and it should be one of: grouped or stacked Default: grouped |

chart.yaxispos | The position of the Y axis. Works with regular and grouped charts. Can be either center or left. Default: left |
chart.key | An array of key information. Default: [] (An empty array) |
chart.key.background | The color of the key background. Typically white, you could set this to something like rgba(255,255,255,0.7) to allow people to see things behind it. Default: white |
chart.key.position | Determines the position of the key.Either graph (default), or gutter. Default: graph |
chart.key.shadow | Whether a small drop shadow is applied to the key. Default: false |
chart.contextmenu | An array of context menu items. You cannot have context menus AND tooltips, only one or the other. More information on context menus is here. Default: [] (An empty array) |
chart.units.pre | The units that the X axis is measured in. This string is displayed BEFORE the actual number, allowing you to specify values such as "$50". Default: none |
chart.units.post | The units that the X axis is measured in. This string is displayed AFTER the actual number, allowing you to specify values such as "50ms". Default: none |
chart.vmargin | The vertical margin that is applied to each individual bar. Default: 3 |
chart.strokestyle | The color of the outlines of the bars. Default: black |
chart.tooltips | An array of tooltips for the chart. Default: An empty array |
chart.tooltip.effect | The visual effect used when showing tooltips. Can be either fade or expand. Default: fade |
chart.annotatable | Whether annotations are enabled for the chart (ie you can draw on the chart interactively. Default: false |

chart.zoom.mode | Can be used to control whether the zoom is in thumbnail or canvas mode. Possible values are: thumbnail and canvas. Default: canvas |
chart.zoom.factor | This is the factor that the graph will be zoomed by (bigger values means more zoom) Default: 1.5 |
chart.zoom.fade.in | Whether the zoomed canvas fades in or not. This also can be used to control the fade in for the zoom in thumbnail mode. Default: true |
chart.zoom.fade.out | Whether the zoomed canvas fades out or not. This also can be used to control the fade in for the zoom in thumbnail mode. Default: true |
chart.zoom.hdir | The horizontal direction of the zoom. Possible values are: left, center, right Default: right |
chart.zoom.vdir | The vertical direction of the zoom. Possible values are: up, center, down Default: down |
chart.zoom.delay | The delay (in milliseconds) between frames. Default: 50 |
chart.zoom.frames | The number of frames in the zoom animation. Default: 10 |
chart.zoom.shadow | Whether or not the zoomed canvas has a shadow or not. Default: true |
chart.zoom.thumbnail.width | When the zoom is in thumbnail mode, this is the width (in pixels) of the thumbnail. Default: 75 |
chart.zoom.thumbnail.height | When the zoom is in thumbnail mode, this is the height (in pixels) of the thumbnail. Default: 75 |
