Now, mimic a good chunk of section 5 (and some others) of the [TauCharts basic examples](http://api.taucharts.com/basic/index.html). Interestingly enough, faceted charts work without any real code changes:
```{r charts_1}
tauchart(scatter_dat) %>%
tau_point("cycleTime", "effort", "team", "count")
```
### ordered factors!
```{r charts_ordered}
scatter_dat %>%
{
data.frame(
.,
cycleTimeFactor =factor(.$cycleTime,
levels=rev(unique(.$cycleTime)),
ordered=TRUE)
)
} %>%
tauchart %>%
tau_point("cycleTimeFactor", "effort", "team", "count")
```
### custom colors!
```{r charts_2}
tauchart(scatter_dat) %>%
tau_point("cycleTime", "effort", "team", "count") %>%
tau_color_manual(c("orange", "green", "black"))
tauchart(line_dat) %>%
tau_line("date", "count", "type") %>%
tau_guide_x(label="Month") %>%
tau_guide_y(label="Count of completed entities", label_padding=50) %>%
tau_guide_padding(70, 70, 10, 10)
tauchart(bar_dat) %>% tau_bar("team", "effort")
tauchart(bar_dat) %>% tau_bar("team", "effort", "priority")
tauchart(bar_dat) %>% tau_bar("effort", "team", horizontal=TRUE)
tauchart(bar_dat) %>% tau_bar("effort", "team", "priority", horizontal=TRUE)
```
### legendary!
```{r chart_leg}
tauchart(car_dat) %>%
tau_point("power", "co2", color="euroEco") %>%
tau_legend()
```
### tooltips!
```{r chart_tips}
tauchart(car_dat) %>%
tau_point("power", "co2", color="euroEco") %>%
tau_legend() %>%
tau_tooltip()
```
### basic facets!
```{r charts_3}
print(car_dat)
tauchart(car_dat) %>%
tau_point(c('euroEco', 'co2'), c('power', 'hp'))
```
### scatterplot matrices!
```{r charts_4}
tauchart(splom_dat) %>%
tau_point(c("param1", "value1"), c("param2", "value2"))
```
### trends!
```{r trends}
tc <- tauchart(car_dat) %>%
tau_point( "hp", c("euroEco","co2"), color = "euroEco" ) %>%
tau_legend( ) %>%
tau_tooltip( )
tc %>%
tau_trendline( ) #using defaults
tc %>%
#type does not seem to work as expected
# so use models instead to change default type or order of dropdown
tau_trendline( models = c( "logarithmic", "exponential" ) )
tc %>%
# start with unclicked TREND LINE
tau_trendline( showTrend = FALSE )
tc %>%
#take the fun away from the user
tau_trendline( showPanel = FALSE )
```
## Now do some other things outside the examples
### customize y axis labels!
```{r custom_1}
how_good <- structure(list(
Ranking = structure(
1:5, .Label = c("Bottom", "Bellow Average",
"Average", "Above Average", "Top"), class = "factor"
), Prob = c(30L, 10L, 15L, 40L, 5L)/100
), .Names = c("Ranking", "Prob"), row.names = c(NA,-5L), class = "data.frame")
# NOTE my division by 100 in Prob above
tauchart(how_good) %>%
tau_bar(x="Ranking", y="Prob") %>%
tau_guide_y(tick_format="%")
```
### the whole shebang!
```{r shebang}
data(cars_data)
tauchart(cars_data) %>%
tau_point("milespergallon", c("class", "price"), color="class") %>%
tau_legend() %>%
tau_trendline() %>%
tau_tooltip(c("vehicle", "year", "class", "price", "milespergallon"))
```
### custom CSS rules!
```{r custom_styles}
make_black_tooltip <- function(tau) {
tau %>%
tau_add_css_rule(".tau-chart__tooltip { background: black; color: white; }") %>%
tau_add_css_rule(".tau-chart__tooltip__exclude:hover { color: #65717f; background: linear-gradient(to right, rgba(255, 255, 255, 0) 100%, rgba(235, 238, 241, 0.9) 0%); }") %>%
tau_add_css_rule(".tau-chart__tooltip__exclude { color: white; }") %>%
tau_add_css_rule(".tau-chart__tooltip__list__elem { color: white; }") %>%
tau_add_css_rule(".tau-chart__tooltip__list__elem:first-child { color: white; font-weight: bold; }") %>%
tau_add_css_rule(".tau-chart__tooltip__gray-text { color: white; font-weight: bold; }")
}
tauchart(mtcars) %>%
tau_point("wt", "mpg", color="cyl") %>%
tau_color_manual(c("blue", "maroon", "black")) %>%
tau_tooltip() %>%
make_black_tooltip()
```
alternatively
```{r multi_styles}
tauchart(mtcars) %>%
tau_point("wt", "mpg", color="cyl") %>%
tau_color_manual(c("blue", "maroon", "black")) %>%
tau_tooltip() %>%
tau_add_css_rule(c(".tau-chart__tooltip { background: black; color: white; }",
".tau-chart__tooltip__exclude:hover { color: #65717f; background: linear-gradient(to right, rgba(255, 255, 255, 0) 100%, rgba(235, 238, 241, 0.9) 0%); }",
".tau-chart__tooltip__exclude { color: white; }",
".tau-chart__tooltip__list__elem { color: white; }",
".tau-chart__tooltip__list__elem:first-child { color: white; font-weight: bold; }",
".tau-chart__tooltip__gray-text { color: white; font-weight: bold; }"))
```
